DESCRIPTION

The ADS7834 is a 12-bit sampling analog-to-digital converter

(A/D) complete with sample/hold, internal 2.5V reference,

and synchronous serial interface. Typical power dissipation

is 11mW at a 500kHz throughput rate. The device can be

placed into a power-down mode that reduces dissipation to

just 2.5mW. The input range is zero to the reference voltage,

and the internal reference can be overdriven by an external

voltage.

Low power, small size, and high speed make the ADS7834

ideal for battery-operated systems such as wireless

communication devices, portable multi-channel data loggers,

and spectrum analyzers. The serial interface also provides

low-cost isolation for remote data acquisition. The ADS7834

is available in a plastic mini-DIP-8 or an MSOP-8 package

and is ensured over the –40°C to +85°C temperature range.
