ADS7810 (NRND)

12-Bit 800kHz Sampling CMOS Analog-to-Digital Converter

 

Not Recommended for New Designs (NRND)

Replaced By ADS8558 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. 6 channel simultaneous sampling ADC with equivalent performance and smaller package
ADS8504 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. Lower sampling rate (250kSPS) with improved linearity and lower power
ADS7835 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. Lower sampling rate (500kSPS), equivalent performance with +/-2.5V input configuration range and serial interface
ADS7886 – The device has the SAME FUNCTIONALITY as the compared device, but is not pin-for-pin equivalent and may not be parametrically equivalent. 5V Unipolar device with serial output interface, higher sampling rate (1MSPS), lower power, and smaller package

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.

Description

The ADS7810 is a complete 12-bit sampling analog-to-digital converter (A/D) using state-of-the-art CMOS structures. It contains a complete 12-bit capacitor-based SAR A/D with inherent S/H, reference, clock, interface for microprocessor use, and 3-state output drivers.

The ADS7810 is specified at an 800kHz sampling rate, and ensured over the full temperature range. Laser-trimmed scaling resistors provide the industry-standard ±10V input range, while an innovative design allows operation from ±5V supplies.

The 28-pin ADS7810 is available in a plastic SOIC fully specified for operation over the industrial –40°C to +70°C range.
