TI microPOWER Data Converters | Texas Instruments
Compare the energy needed to take a sample with the power needed to hold an analog output.
Which direction does the signal travel?
The ADS8325 digitizes an analog input. This 16-bit sampling ADC can produce up to 100,000 conversions per second and sends the results over a serial output. Size the acquisition interval for the sensor and its source impedance.
The DAC8560 takes the opposite path. It generates a voltage from a 16-bit code and includes a 2.5 V reference. Its output settling and reference behavior matter when setting a bias or a calibration voltage.
For a battery-powered instrument, count the conversions taken in each wake interval and the time the DAC must hold its output. A shared resolution and a low-power label do little to predict that duty-cycle budget.
