The ADS7835 is a 12-bit, sampling analog-to-digital converter (A/D) complete with sample-and-hold (S/H), internal 2.5V reference, and synchronous serial interface. Typical power dissipation is 17.5mW at a 500kHz throughput rate. The device can be placed into a power-down mode which reduces dissipation to just 2.5mW. The input range is –VREF to +VREF, and the internal reference can be overdriven by an external voltage.

Low power, small size, and high speed make the ADS7835 ideal for battery-operated systems such as wireless communication devices, portable multichannel data loggers, and spectrum analyzers. The serial interface also provides low cost isolation for remote data acquisition. The ADS7835 is available in an MSOP-8 package and is guaranteed over the –40°C to +85°C temperature range.
