Texas Instruments ADS7809U
- Part Number:
- ADS7809U
- Manufacturer:
- Texas Instruments
- Ventron No:
- 3012474-ADS7809U
- Description:
- 16-Bit 10us Serial CMOS Sampling Analog-to-Digital Converter
- Datasheet:
- ads7809
Description
The ADS7809 is a 16-bit sampling Analog-to-Digital (A/D) converter using CMOS structures. It contains a 16-bit capacitor-based Successive Approximation Register (SAR) A/D converter with sample-and-hold, reference, clock, and a serial data interface. Data can be outputted using the internal clock or synchronized to an external data clock. The ADS7809 also provides an output synchronization pulse for ease of use with standard DSP processors.
The ADS7809 is specified at a 100kHz sampling rate and over the full temperature range. Laser-trimmed scaling resistors provide various input ranges including ±10V and 0V to 5V, while an innovative design operates from a single 5V supply, with power dissipation under 100mW.
The ADS7809 is available in a 0.3" SO-20 and is fully specified for operation over the industrial -40°C to 85°C range.
