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.
