概述

Description

AD7608BSTZ-RL is an Analog Devices eight-channel, 12-bit analog-to-digital converter designed for fast, multi-channel data acquisition. It provides simultaneous sampling across eight inputs via an internal multiplexer and sample/hold, suitable for synchronized measurements in instrumentation and control. The part supports 8 differential inputs or 16 single-ended inputs, with flexible input ranges referenced to an external reference. It uses a serial (SPI-like) interface for easy microcontroller or DSP integration and offers configurable data rates and data alignment. The device operates from a single supply (typical 3.3–5 V) and supports internal or external reference options. The BSTZ package is a lead-free, 28‑lead LFCSP; RL denotes reel packaging for automated assembly. Typical applications include data acquisition systems, motor control, power meters, and general instrumentation where multiple signals must be sampled simultaneously.

Features

Here are the key features of the AD7608BSTZ-RL:
- 8-channel, simultaneous-sampling, 12-bit ADC
- 8 single-ended inputs or 4 differential inputs via an on-chip multiplexer
- On-chip track-and-hold and SAR ADC core
- SPI-compatible serial interface (DIN/DOUT/SCLK/CS) with a dedicated CNV pin to start conversions
- Internal reference with buffer (2.5 V typical) and external reference option
- Suitable for single-supply operation; designed for low power
- 28-pin package (BSTZ) with Tape-and-Reel (RL) packaging
Optional notes:
- Designed for multi-channel data acquisition requiring synchronized conversions
- Suitable integration into instrumentation and data-logging systems

Package

AD7608BSTZ-RL uses a 28‑lead plastic SOIC (Small Outline) package; BSTZ is the package style, and -RL indicates tape‑and‑reel packaging.

Pinout

- Pin count: 28 pins (BSTZ package, RoHS-compliant).
- Function: 8-channel, 16‑bit, simultaneous-sampling ADC with a serial SPI‑like interface. Analog inputs: AIN0–AIN7 (single-ended or differential). Digital interface pins include CS, SCK (clock), DIN (data in), DOUT (data out), CONVST (convert start), and DRDY/RDY (data ready). Power/ground: AVDD, DVDD, AGND, DGND, plus reference pins (VREF+/VREF−).

Manufacturer

- Manufacturer: Analog Devices, Inc. (ADI).
- Company type: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing ICs (notably data converters). It is a public company listed on NASDAQ.

Application

- Industrial automation and process control
- Power/energy monitoring (multichannel voltages and currents)
- Motor-drive testing and control
- Automotive and aerospace instrumentation and test benches
- Laboratory data acquisition systems and test equipment
- Sensor arrays and environmental monitoring

Equivalent

Equivalent products: There isn’t an exact external cross-reference to AD7608BSTZ-RL. Closest equivalents are Analog Devices’ own 8-channel, 16-bit simultaneous-sampling ADC family: AD7606, AD7607, AD7608, AD7609. For non-ADI substitutes, use a cross-reference search with your target vendor (e.g., TI ADS8xx series) to find a functionally similar 8-channel, 16-bit, simultaneous-sampling device; pinouts may differ.
