- Part Number:
- AD7870SQ
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3014683-AD7870SQ
- Description:
- IC ADC 12BIT SAMPLING 3V 24-CDIP
- Datasheet:
- AD7870SQ
Description
The AD7870/AD7875/AD7876 are complete, 12-bit analog-to-digital converters (ADCs) that integrate a track-and-hold amplifier, 8 µs successive approximation ADC, 3 V buried Zener reference, and versatile interface logic on a single chip. They feature a self-contained internal clock, laser-trimmed for accurate conversion time control, and offer a choice of parallel, byte, or serial digital interface formats.
Features
Complete 12-bit ADC on a single chip
2 µs track-and-hold amplifier
8 µs ADC
On-chip reference
Laser-trimmed clock
Parallel, byte, and serial digital interface
72 dB SNR at 10 kHz input frequency (AD7870, AD7875)
57 ns data access time
Low power: -60 mW typical
Variety of input ranges:
±3 V for AD7870
0 V to 5 V for AD7875
±10 V for AD7876
Applications
Data acquisition systems
Process control
Medical instrumentation
Audio signal processing
