概述

Description

The AD7722ASZ is Analog Devices’ dual-channel, 16-bit analog-to-digital converter (ADC) in the ASZ package. It provides high-speed conversion of two analog inputs with a serial (SPI-like) digital output, suitable for instrumentations, data acquisition, and communications systems. Key features typically include a track-and-hold input stage, differential input options, and low-power operation, with configurable input ranges and references. For exact performance (sampling rate, input configuration, power, and package details), consult the AD7722 datasheet.

Features

AD7722ASZ features (concise):
- Dual 16-bit analog-to-digital converters
- Multiplexed input with track/hold for each channel
- Simultaneous sampling option across two channels
- SPI-compatible serial interface (DIN, DOUT, SCLK, CS) with CONVST control
- Internal reference (e.g., 2.5 V) plus external reference input
- Supports unipolar and bipolar input ranges
- Single-supply operation: 2.7 V to 5.25 V
- Low-power modes and fast wake-up
- Industrial temperature range (-40°C to +85°C)
- 28-lead ASZ package (compact SOIC-style)

Pinout

- Pin count: 28 pins (28‑lead package).
- Function: Dual 12‑bit Analog‑to‑Digital Converter (ADC) with a serial (SPI‑like) interface.

Manufacturer

Analog Devices, Inc. (Analog Devices) manufactures the AD7722ASZ. Analog Devices is an American multinational semiconductor company that designs and produces analog, mixed-signal, and digital signal processing integrated circuits, including data converters (ADCs/DACs) and sensors.
