Analog Devices Inc. AD7708BRZ
- Part Number:
- AD7708BRZ
- Manufacturer:
- Analog Devices Inc.
- Ventron No:
- 3026524-AD7708BRZ
- Description:
- IC ADC 16BIT R-R 8/10CH 28SOIC
- Datasheet:
- AD7708BRZ
Description
The AD7708/AD7718 are 8-/10-channel, low-voltage, low-power, Σ-Δ ADCs with programmable gain front ends. The AD7718 has a 24-bit resolution, while the AD7708 has a 16-bit resolution. Both devices are factory-calibrated and feature a single conversion cycle setting. They also have simultaneous 50 Hz and 60 Hz rejection and VREF Select™ capability for absolute and ratiometric measurement. The operation can be optimized for analog performance (CHOP = 0) or channel throughput (CHOP = 1).
