ADS7834
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. Typi-
cal power dissipation is 11mW at a 500kHz through-
put rate. The device can be placed into a power-down
mode which 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-chan-
nel 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 guaranteed
over the –40°C to +85°C temperature range.
