GENERAL DESCRIPTION The Analog Devices, Inc., amplifier mezzanine card (AMC) analog-to-digital converter (ADC) driver evaluates the performance of amplifiers in 8-lead, single and dual SOIC, 6-lead single SOT23, 8-lead dual MSOP, and 16-lead LFCSP packages. This add on board can be inserted on ADC evaluation boards using its 7-pin header. Figure 1 shows the AMC mounted on an Analog Devices, Inc., ADC evaluation board.

The AMC can support any of Analog Devices operational amplifiers and ADC drivers in different packages. The user can configure the ADC driver as a Sallen-Key low-pass, high-pass, or band-pass filter, as a multiple feedback low-pass, high-pass, or band-pass filter, or as an inverting and noninverting operational amplifier. The user can also configure the AMC to drive a single-ended, fully differential, or a single-ended signal to a differential ADC.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The AMC evaluation board accepts 0402 or 0603 surface mount technology (SMT) components, 1206 bypass capacitors, and 2.54 mm headers.

All components are placed on the primary side. No components are placed on the secondary side.

BOARD ASSEMBLY INTRODUCTION The AMC allows the user to set the ADC driver to different types of active filter configurations and op amp layouts such as inverting and noninverting. The user can also configure the AMC to drive a single-ended, fully differential, and a single-ended signal to differential ADC.

SINGLE AMPLIFIER The AMC for single amplifiers can support ADC drivers that come in 8-lead SOIC and 6-lead SOT23 packages (see Figure 2 and Figure 3).

Figure 2. Example of a Single Amplifier in SOIC Package

Figure 3. Example of a Single Amplifier on SOT23 Package

Low-Pass Filter

The user can configure a Sallen-Key, low-pass filter on the AMC.

Figure 4. Sallen-Key, Low-Pass Filter

Place user defined capacitors on the R7 and R8 resistors, user defined capacitors on the C3 and C4 board positions, and resistors on the R1, R2, R3, R4, R9, R10, R17, and R18 resistors. Place a 0 Ω resistor on C5 and C6 for the feedback to achieve the Sallen-Key low-pass filter configuration.

Multiple Feedback, Low-Pass Filter

The user can configure a multiple feedback, low-pass filter on the AMC.

Place a 0 Ω resistor on R7 and R8 to connect the noninverting input to ground, and place the user defined capacitors on the C1, C2, C5, and C6 capacitors and the resistors on the R15, R16, R17, R18, R19, and R20 resistors.

High-Pass Filter

Place capacitors on the R1, R2, R3, and R4 resistors, resistors on the R7, R8, R9, R10, R17, and R18 resistors, and resistors on the C3 and C4 capacitors. Place a 0 Ω resistor on C5 and C6 to configure the AMC board into a Sallen-Key high-pass filter. This configuration is similar to the low-pass filter except replace the resistors on the noninverting input to capacitors and vice versa.

Noninverting Configuration

To configure the AMC board into a noninverting amplifier, place 0 Ω resistors at R1, R2, R3, and R4 to connect the input to the noninverting input of the amplifier. To set the gain of the amplifier, place the user defined resistor values on R9 and R10 for RF and R17 and R18 for RG and place a 0 Ω resistor on C5 and C6 to connect RG to ground.

DUAL AMPLIFIER The AMC also supports dual amplifiers that can aid op amps and ADC drivers that come in 8-lead MSOP and 8-lead SOIC packages. Dual amplifier have two amplifiers inside one package.

Figure 26. Dual Amplifier, 8-Lead MSOP (RM) and 8-Lead SOIC (R) Package

Low-Pass Filter

Similar to single amplifiers, the user can configure the dual amplifier to different types of filter topologies except instead of two ICs, the user only uses one IC.

Figure 27. Sallen-Key, Low-Pass Filter 8-Lead SOIC, Dual Board Configuration

Figure 28. Sallen-Key, Low-Pass Filter 8-Lead MSOP, Dual Board

Configuration

A Sallen-Key, low-pass filter can also be configured on the dual AMC. To set the cutoff frequency of the filter, place the user defined resistor values for the filter on R1 and R3 on one amplifier and R2 and R4 for the other one. Place the user defined capacitor values on R7 and C3 for the first amplifier and R8 and C4 for the second amplifier. To set the gain of the amplifier, place the necessary feedback resistors on R9 and R10 for the first and

second amplifiers, as well as RG on R17 and R18. Then, place a 0 Ω resistor on C5 and C6 to connect RG straight to ground.

Figure 29. Multiple Feedback Low-Pass Filter 8-Lead SOIC, Dual AMC

Configuration

Figure 30. Multiple Feedback, Low-Pass Filter 8-Lead MSOP, Dual AMC

Configuration

For a multiple feedback configuration, place the user defined resistor values on R15, R17, and R19 for the first amplifier and R16, R18, and R20 for the second amplifier. Place the capacitors on C1 and C5 for the first amplifier and C2 and C6 for the second amplifier.

High-Pass Filter

To achieve a Sallen-Key, high-pass filter configuration, place a 0 Ω resistor at C5 and C6, then place the user defined resistor values for the gain setting on R9 and R10 (RF) and R17 and R18 (RG). Place resistors on R7, R8, C3, and C4 as well as capacitors on R1, R2, R3, and R4 to dictate the cutoff frequency. The configuration is almost the same as in Sallen-Key, low-pass filter, but the resistors and capacitors interchange in the noninverting input of the amplifier.

In the case of a multiple feedback, high-pass filter, place the 0 Ω resistor on R7 for the first amplifier and R8 for the second. Then, place the user defined resistor values on C5 and R9 for the first amplifier and C6 and R10 for the second amplifier. Then, place capacitors on R15, R17, and R19 for the first amplifier and on R16, R18, and R20 for the second amplifier.

Band-Pass Filter

For a band-pass filter in a Sallen-Key configuration, connect VCM to ground and place the user defined resistor values to design the filter on R1, R2, R7, R8, C3, C4, R4, R3, R5, and R6. To set the gain of the amplifier, place RF on R9 and RG on R13. Do the same for the second amplifier with RG on R14 and RF on R10.
