概要
Description
The ADS7807U is a 12-bit, 100 kSPS (kilo-samples per second) successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features low power consumption (typically 35 mW) and operates on a ±5V supply, making it suitable for precision data acquisition in industrial and instrumentation applications.
Key features:
- 12-bit resolution with ±1 LSB linearity error
- 100 kSPS conversion rate
- Internal reference and track/hold for simplified design
- Parallel interface for easy microcontroller interfacing
- Wide input range (±10V, ±5V, 0–5V, or 0–10V selectable)
The ADS7807U is ideal for battery-powered systems, medical devices, and process control due to its high accuracy and low power consumption. Its robust performance and ease of integration make it a reliable choice for moderate-speed, high-resolution ADC needs.
