Overview

Description

The AD1674JNZ is a 12-bit, 100 kSPS (kilo-samples per second) successive approximation analog-to-digital converter (ADC) from Analog Devices. It integrates a sample-and-hold amplifier (SHA), a voltage reference, and a high-speed parallel interface, making it suitable for precision data acquisition.
Key features:
- Resolution: 12 bits
- Throughput: 100 kSPS
- Input Range: ±5V, ±10V, or 0V to +10V (software-selectable)
- On-Chip Reference: 10V ±1%
- Interface: Parallel (8/12-bit selectable)
- Power Supply: ±12V and +5V
Applications include industrial control, instrumentation, and high-speed data logging. The JNZ suffix denotes a plastic DIP-28 package.
Its low power consumption (≤ 450mW) and fast conversion time (10µs) make it a reliable choice for embedded systems requiring moderate-speed, high-accuracy conversions.
For detailed specs, refer to the datasheet on Analog Devices' website.
