Texas Instruments ADS7844N/1K
- Part Number:
- ADS7844N/1K
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3008506-ADS7844N/1K
- Description:
- 12-Bit, 8-Channel Serial Output Sampling Analog-To-Digital Converter
- Datasheet:
- ads7844
Description
The ADS7844 is an 8-channel, 12-bit sampling analog-to-digital converter (ADC) with a synchronous serial interface. It operates on a single supply voltage ranging from 2.7V to 5V. The reference voltage (VREP) can be adjusted between 100mV and Vee-, providing a corresponding input voltage range of 0V to VREP. The device features a shutdown mode that reduces power dissipation to under 1µW. The ADS7844 is available in a 20-lead QSOP package and a 20-lead SSOP package, and is specified for operation over the -40°C to 85°C temperature range.
Features
Single supply operation: 2.7V to 5V
8-channel single-ended or 4-channel differential input
Up to 200kHz conversion rate
±1 LSB maximum INL and DNL
No missing codes
72dB SINAD
Serial interface
20-lead QSOP and 20-lead SSOP packages
Alternate source for MAX147
Applications
Data acquisition
Test and measurement
Industrial process control
Personal digital assistants
Battery-powered systems
