- 3006231-AD7891YSZ-2
- Description:
- IC DAS 12BIT 8CH 44-MQFP
- ECAD Model:
-
- Datasheet:
- AD7891YSZ-2
Description
The AD7891 is an 8-channel, 12-bit data acquisition system that combines an input multiplexer, track/hold amplifier, 12-bit ADC, 2.5 V reference, and high-speed interface on a single chip. It operates from a single 5 V supply and accepts various analog input ranges. The AD7891 provides the option of either a parallel or serial interface structure determined by the MODE pin. It has standard control inputs and fast data access times for both interfaces, ensuring easy interfacing with modern microprocessors, microcontrollers, and digital signal processors.
Features
Fast 12-bit ADC with 1.6 μs conversion time
8 single-ended analog input channels
Overvoltage protection on each channel
Selection of input ranges:
±5 V, ±10 V for AD7891-1
0 to 2.5 V, 0 to 5 V, ±2.5 V for AD7891-2
2.5 V reference
Standby mode (75 μW typ)
Single-supply, low power operation (100 mW max)
Parallel and serial interface
On-chip track/hold amplifier
Applications
Data acquisition systems
Motor control
Mobile communication base stations
