DESCRIPTIONThe ADS7844 is an 8-channel, 12-bit sampling analog-to-
digital converter (ADC) with a synchronous serial interface.
Typical power dissipation is 3mW at a 200kHz throughput
rate and a +5V supply. The reference voltage (VREF) can be
varied between 100mV and VCC, providing a corresponding
input voltage range of 0V to VREF. The device includes a
shutdown mode that reduces power dissipation to under
1μW. The ADS7844 is ensured down to 2.7V operation.
Low power, high speed, and onboard multiplexer make the
ADS7844 ideal for battery-operated systems such as personal
digital assistants, portable multichannel data loggers, and
measurement equipment. The serial interface also provides
low-cost isolation for remote data acquisition. The ADS7844
is available in a 20-lead QSOP package and the MAX147
equivalent 20-lead SSOP package and is ensured over the
–40°C to +85°C temperature range.
