Description
The AD7890 is an 8-channel, 12-bit data acquisition system that integrates an input multiplexer, track/hold amplifier, 12-bit ADC, 2.5 V reference, and high-speed serial interface onto a single chip. It operates from a single 5 V supply and accepts analog input ranges of ±10 V, 0 V to 4.096 V, or 0 V to 2.5 V.
Features
Fast 12-bit ADC with 5.9 µs conversion time
Eight single-ended analog input channels
Selectable input ranges: ±10 V, 0 V to 4.096 V, or 0 V to 2.5 V
Separate access to multiplexer and ADC
On-chip track/hold amplifier
On-chip reference
High-speed, flexible serial interface
Single supply, low-power operation (50 mW maximum)
Power-down mode (75 µW typical)
Applications
Data acquisition systems
Process control
Industrial automation
Medical instrumentation
Test and measurement equipment
