Texas Instruments ADS7861IRHBT
- Part Number:
- ADS7861IRHBT
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3008639-ADS7861IRHBT
- Description:
- IC ADC 12BIT DUAL 4-INPUT 32QFN
- ECAD Model:
-
- Datasheet:
- ADS7961
Description
The ADS7861 is a dual, 12-bit, 500kSPS analog-to-digital (A/D) converter with four fully differential input channels. These channels are grouped into two pairs for high-speed, simultaneous signal acquisition. Inputs to the sample-and-hold amplifiers are fully differential and maintained differential to the input of the A/D converter. This provides excellent common-mode rejection of 80dB at 50kHz, which is important in high-noise environments.
The ADS7861 offers a high-speed, dual serial interface and control inputs to minimize software overhead. The output data for each channel is available as a 12-bit word. The ADS7861 is offered in both an SSOP-24 and a QFN-32 package and is fully specified over the -40°C to 125°C operating range.
Features
4 input channels
Fully differential inputs
2µs total throughput per channel
No missing codes
1MHz effective sampling rate
Low power: 40mW
SSI serial interface
Operating temperature range: -40°C to 125°C
Applications
Motor control
Multi-axis positioning systems
3-phase power control
