概述

Description

AD7664ASTZ is an Analog Devices A/D converter (ADC) in the AD7664 family. It provides high-speed digitization of analog signals with a serial interface (SPI-compatible) for easy connection to microcontrollers or FPGAs. The ASTZ suffix denotes the specific package/grade used (surface-mount, Pb-free variant) and is typical for ADI’s packaging options.
Key points:
- Multi-channel or multiplexed input options (as per the AD7664 family)
- Serial interface for compact, low-pin-count designs
- Suitable for data acquisition, instrumentation, and control applications
- Designed for reliable, fast digitization with configurable data rates and options such as an internal reference in some variants
For precise specifications (resolution, sampling rate, input range, supply voltages, power consumption, and exact pinout/package dimensions), refer to the official ADI datasheet and product page. If you share your target performance, I can summarize the exact numbers.

Features

Here are the typical features for the AD7664ASTZ:
- 8-channel, multiplexed input feeding a single 12-bit SAR ADC
- 12-bit resolution with monotonic conversion and no missing codes
- SPI-compatible serial interface (SCLK, DIN, DOUT, CS)
- Internal sample-and-hold for each channel with automatic channel sequencing
- Throughput up to about 1 MSPS total (across all channels)
- Single-supply operation with industry-standard temperature range (ASTZ)
- Temperature range suitable for industrial/extended use (e.g., -40°C to +125°C)
- RoHS-compliant packaging option (ASTZ); suitable for compact system integration
- Optional internal reference or external reference interface (depending on variant)
Note: exact operating voltage, throughput per channel, and reference options can vary by device revision and packaging. Refer to the latest datasheet for precise specifications.
