AD7607BSTZ-RL

ADCs/DACs - Special Purpose Overview

The AD7607BSTZ-RL is an 8-channel, 14-bit simultaneous sampling analog-to-digital data acquisition system (DAS) from Analog Devices Inc. It integrates analog input clamp protection, a second-order antialiasing filter with a 22 kHz cutoff, track-and-hold amplifiers, and a 14-bit SAR ADC. The device supports true bipolar input ranges of ±10 V and ±5 V via a single 5 V analog supply and a 2.3 V to 5.25 V digital drive supply. It achieves a throughput rate of 200 kSPS across all channels with a typical power consumption of 100 mW at maximum speed. Key performance metrics include 85.5 dB SNR at 50 kSPS, ±0.25 LSB INL/DNL, and 7 kV ESD protection on analog inputs.

ADCs/DACs - Special Purpose Procurement Notes

Verify the ordering suffix 'RL' indicates reel packaging when sourcing components. Confirm the 'B' grade designation corresponds to the industrial temperature range of −40°C to +85°C as specified in the datasheet. Ensure the 64-lead LQFP package type matches the target PCB footprint requirements. Cross-reference the specific revision level (Rev. D) for any updates to timing parameters or patent notes relative to design documentation.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring synchronized multi-channel acquisition without external multiplexers. The integrated antialiasing filter simplifies board layout by eliminating external passive components. Choose between internal or external references based on required accuracy; the internal reference offers convenience while external options may provide higher stability. Ensure the host logic voltage aligns with the VDRIVE supply range of 2.3 V to 5.25 V for compatible interface signaling.

ADCs/DACs - Special Purpose Part Context

The AD7607 belongs to a family of high-resolution, bipolar input, simultaneous sampling DAS solutions. It is pin-compatible with the 16-bit AD7606 and the 18-bit AD7608, allowing for scalable design upgrades within the same package form factor. This compatibility facilitates migration paths for systems requiring increased resolution without redesigning the mechanical enclosure or primary PCB layout.

ADCs/DACs - Special Purpose Replacement Considerations

Pin-compatible alternatives include the AD7606 (16-bit) and AD7608 (18-bit). These devices share the same 64-lead LQFP footprint and interface protocols but offer higher resolution. Verify that the system's processing capability can handle the increased data width if upgrading to these variants.
