Product details
Overview
EVAL-AD7684SDZ from Analog Devices is a 6-lead SOT-23 ADC driver evaluation board designed to interface with the AD7684 16-bit PulSAR® successive-approximation ADC and other compatible 8-/10-lead PulSAR evaluation boards. It supports single-ended and differential input configurations, features edge-mounted headers for rapid prototyping, and includes standalone power supply adjustment capability.
For engineers reviewing the EVAL-AD7684SDZ datasheet, EVAL-AD7684SDZ pinout, EVAL-AD7684SDZ application, or EVAL-AD7684SDZ equivalent, this board enables fast amplifier characterization in SOT-23 packages-particularly when evaluating signal conditioning for high-resolution data acquisition systems requiring low-noise, wide-bandwidth drive into 14-/16-/18-bit SAR ADCs.
Technical Context
The EVAL-AD7684SDZ is an add-on daughterboard that mounts via a 7-pin header onto host PulSAR evaluation platforms (e.g., 8-lead or 10-lead variants). It accommodates dual SOT-23-6 amplifiers (AD8061/AD8063) and provides user-configurable resistor/capacitor networks to set gain, common-mode voltage, and filtering.
It supports two primary signal paths: driving a single-ended ADC input using one amplifier channel, or converting a single-ended source into a differential signal for a differential-input ADC using both amplifier channels in complementary configuration. Power routing requires removal of specific resistors (R20, R21, R28, R35, R36, R40) on the host ADC evaluation board per UG-340 schematics.

FAQ
What is the primary function of the EVAL-AD7684SDZ?
The EVAL-AD7684SDZ is an add-on ADC driver evaluation board that enables rapid characterization of SOT-23-6 amplifiers-such as the AD8061 or AD8063-when driving the AD7684 16-bit PulSAR ADC or other compatible 14-/16-/18-bit SAR converters. It provides configurable signal conditioning paths and independent power supply control for optimizing amplifier performance in high-resolution data acquisition setups.
Which ADC evaluation boards is EVAL-AD7684SDZ compatible with?
EVAL-AD7684SDZ is explicitly compatible with Analog Devices' 8-lead and 10-lead PulSAR ADC evaluation boards, including those for the AD7683, AD7684, AD7694 (16-bit), AD7942/AD7946 (14-bit), AD7685–AD7688/AD7693/AD7980–AD7983/AD7988-5 (16-bit), and AD7690–AD7691/AD7982–AD7984/AD7989-5 (18-bit) families. Mounting uses a standard 7-pin header interface.
Does EVAL-AD7684SDZ include active components?
Yes, EVAL-AD7684SDZ includes two populated SOT-23-6 amplifier ICs-specifically AD8061 or AD8063 devices-as confirmed in the UG-682 schematic and bill of materials. These are pre-mounted and ready for evaluation without requiring user soldering of the core signal path amplifiers.
How is power routed to the EVAL-AD7684SDZ when mounted?
Power routing to EVAL-AD7684SDZ requires removing six specific resistors (R20, R21, R28, R35, R36, R40) on the host ADC evaluation board to isolate its internal supply paths. External VCC and VEE rails are then applied directly to the EVAL-AD7684SDZ's dedicated supply input pins, enabling independent amplifier bias control without interference from the host board's power distribution.
Can EVAL-AD7684SDZ be used with differential-input ADCs?
Yes, EVAL-AD7684SDZ supports differential drive mode: one amplifier channel generates VOUTP while the other generates VOUTN, allowing conversion of a single-ended input signal into a fully differential output pair. Figure 4 in UG-682 details this configuration, which is optimized for driving differential-input SAR ADCs like the AD7684 in pseudo-differential or true differential acquisition modes.
