AD7606BSTZ

ADCs/DACs - Special Purpose Overview

The AD7606BSTZ is an 8-channel, 16-bit simultaneous sampling data acquisition system (DAS) from Analog Devices. It integrates analog input clamp protection, a second-order antialiasing filter, track-and-hold amplifiers, and a 16-bit SAR ADC. Operating on a single 5 V supply with 2.3 V to 5 V VDRIVE, it supports ±10 V and ±5 V bipolar inputs at up to 200 kSPS per channel. Key electrical parameters include a 95.5 dB SNR, -107 dB THD, ±0.5 LSB INL/DNL, and 1 MΩ input impedance. The device features flexible parallel/serial interfaces, a 2.5 V internal reference, and operates within a -40°C to +85°C temperature range 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 tape/reel specifications. Ensure compatibility with the host logic voltage levels (VDRIVE) for the selected interface mode. Confirm that the thermal management design accounts for the specified power dissipation at the target operating frequency.

ADCs/DACs - Special Purpose Selection Notes

Select the AD7606BSTZ when eight channels of synchronized high-resolution sampling are required. Choose this part over the AD7606-6 or AD7606-4 if all eight channels are necessary. Consider the AD7606B series for newer designs requiring pin-compatible upgrades with potentially enhanced performance characteristics. Ensure the application benefits from the integrated antialiasing filter and high input impedance to simplify external circuitry.

ADCs/DACs - Special Purpose Part Context

The AD7606BSTZ belongs to the AD7606 family, which includes the 6-channel AD7606-6 and 4-channel AD7606-4 variants. These devices share identical functional blocks and interface protocols but differ in channel count. The 'BSTZ' suffix typically denotes the standard commercial grade version in a 64-lead LQFP package. This component serves as a complete DAS solution, reducing the need for external driver amplifiers and discrete filtering components.

ADCs/DACs - Special Purpose Replacement Considerations

The AD7606B is a recommended state-of-the-art alternative with pin-to-pin compatibility. For applications requiring higher resolution, consider the AD7608 or AD7609 series. If fewer channels are sufficient, the AD7606-6 or AD7606-4 may offer cost or power advantages while maintaining the same interface and performance profile.
