AD7607BSTZ

ADCs/DACs - Special Purpose Overview

The AD7607BSTZ is an 8-channel, 14-bit simultaneous sampling analog-to-digital data acquisition system (DAS) from Analog Devices. It integrates a second-order antialiasing filter, track-and-hold amplifier, and a 2.5 V reference buffer. Operating on a single 5 V analog supply and 2.3 V to 5.25 V digital drive voltage, it supports ±10 V and ±5 V true bipolar input ranges with 200 kSPS throughput per channel. Key performance metrics include an 85.5 dB SNR at 50 kSPS, ±0.25 LSB INL/DNL, and 1 MΩ input impedance. The device features analog input clamp protection tolerating up to ±16.5 V and offers flexible parallel or serial interface options in a 64-lead LQFP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with system voltage levels for AVCC and VDRIVE. Confirm that the required oversampling ratios and interface modes align with the design specifications before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when simultaneous sampling across multiple channels is required without external multiplexing. The integrated antialiasing filter simplifies front-end design by eliminating the need for external filters. Consider the power consumption requirements, as standby mode draws typical current of 5 mA while operational mode consumes approximately 100 mW at full speed.

ADCs/DACs - Special Purpose Part Context

The AD7607 belongs to a family of high-resolution data acquisition systems from Analog Devices. It is pin-compatible with other devices in the series offering resolutions from 14 bits to 18 bits, such as the AD7606 and AD7608. This compatibility allows for design scalability within the same footprint while adjusting for resolution and channel count needs.

ADCs/DACs - Special Purpose Replacement Considerations

For direct pin-compatible replacements with different resolutions, consider the AD7606 (16-bit) or AD7608 (18-bit). Verify that the target replacement maintains the same 8-channel configuration and simultaneous sampling capability to ensure functional equivalence in existing designs.
