概述

Description

AD7657BSTZ is an Analog Devices 16‑bit analog-to-digital converter (ADC). It uses a SAR (successive-approximation) architecture with a serial (SPI‑like) interface, suitable for precision data acquisition. Key features typically include differential or single‑ended inputs, optional internal/external reference, and low‑power operation with a ready/clock workflow compatible with microcontrollers. Applications span instrumentation, process control, and general data‑acquisition systems. The BSTZ suffix denotes the specific package/lead‑frame variant (rohs/compliant packaging). For exact specifications (input range, sampling rate, power, timing, and pinout), consult the AD7657 datasheet and packaging table.

Features

Key features of AD7657BSTZ (highlights):
- 8-channel input multiplexer with N-channel simultaneous sampling
- 12-bit SAR (successive-approximation) ADC
- Internal sample-and-hold
- Flexible input config: single-ended or differential inputs
- Data interface: parallel 12-bit outputs (with control signals) and optional serial interface
- External or internal reference support
- Low-power operation with standby/power-down modes
- Industrial temperature range (-40°C to +85°C)
- Package: BSTZ family package (as specified for AD7657BSTZ)
Note: For exact speeds, pinout details, reference options, and timing, please consult the AD7657BSTZ datasheet.

Package

AD7657BSTZ comes in an 8-lead plastic SOIC (SOP-8) package and is RoHS-compliant (Pb-free).

Pinout

Pin count: 28 pins.
Function: AD7657BSTZ is a 16-bit successive-approximation (SAR) ADC with a serial (SPI-compatible) interface, used to convert analog input to digital data. It is packaged in a 28-pin package.
