- Part Number:
- AD7863BRZ-3
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3017184-AD7863BRZ-3
- Description:
- IC ADC 14BIT DUAL 2CHAN 28SOIC
- Datasheet:
- AD7863BRZ-3
Description
The AD7863 is a high-speed, low-power, dual 14-bit analog-to-digital converter (ADC) that operates from a single 5 V supply. It features two 5.2 µs successive approximation ADCs, two track/hold amplifiers, an internal 2.5 V reference, and a high-speed parallel interface. The four analog inputs are grouped into two channels (A and B), each with two inputs (VAI and Vor V and Vs) that can be sampled and converted simultaneously. The AD7863 accepts analog input ranges of ±10 V (AD7863-10), ±2.5 V (AD7863-3), and 0 V to 2.5 V (AD7863-2). It also features overvoltage protection on the analog inputs, allowing input voltages up to ±17 V, ±7 V, or 7 V without damage.
Features
Two fast 14-bit ADCs
Four input channels
Simultaneous sampling and conversion
5.2 µs conversion time
Single supply operation
Selection of input ranges: ±10 V, ±2.5 V, 0 V to 2.5 V

Power-saving mode, 105 µW maximum
Overvoltage protection on analog inputs
14-bit lead compatible upgrade to AD7862
Applications
Data acquisition systems
Process control
Medical instrumentation
Industrial automation
Test and measurement
Audio signal processing
Vibration analysis
