- Part Number:
- AD7899AR-1
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3016031-AD7899AR-1
- Description:
- IC ADC 14BIT 400KSPS 5V 28-SOIC
- ECAD Model:
-
- Datasheet:
- AD7899AR-1
Description
The AD7899 is a fast, low-power, 14-bit analog-to-digital converter (ADC) that operates from a single 5 V supply. It features a 2.2 μs successive-approximation ADC, a track/hold amplifier, a 2.5 V reference, an on-chip clock oscillator, signal conditioning circuitry, and a high-speed parallel interface. The AD7899 accepts analog input ranges of ±10 V, ±5 V, ±2.5 V, 0 V to 2.5 V, and 0 V to 5 V. Overvoltage protection on the analog input allows the input voltage to be exceeded without damaging the part.
Features
Fast (2.2 μs) 14-bit ADC
400 kSPS throughput rate
0.3 ps track/hold acquisition time
Single supply operation
Selection of input ranges: ±10 V, ±5 V, ±2.5 V, 0 V to 2.5 V, and 0 V to 5 V
High-speed parallel interface which also allows interfacing to 3 V processors
Low power, 80 mW typ
Power-saving mode, 20 μW typ
Overvoltage protection on analog inputs
Power-down mode via STBY pin
5 V single supply
Applications
Data acquisition systems
Process control
Medical instrumentation
Industrial automation
Test and measurement equipment
Battery-powered applications
