Analog Input Channel 1. Single-ended analog input with respect to AGND with range
of 0V to V
Analog Input Channel 2. Single-ended analog input with respect to AGND with range
of 0V to V
Analog Input Channel. Single-ended analog input with respect to GND with range of
0V to V
Ground. Connect GND to the GND ground plane.
Analog Ground. Connect AGND directly the GND ground plane.
External Reference Input. REF defines the signal range of the input signal AIN1/AIN2:
0V to V
capacitor.
Positive Supply Voltage. Bypass V
range is 2.2V to 3.6V. For the SOT23 package, V
the input signal AIN: 0V to V
Active-Low Chip-Select Input. The falling edge of CS samples the analog input signal,
starts a conversion, and frames the serial data transfer.
Channel Select. Set CHSEL high to select AIN2 for conversion. Set CHSEL low to
select AIN1 for conversion.
Digital Interface Supply for SCLK, CS, DOUT, and CHSEL. The OVDD range is 1.5V
to V
Three-State Serial Data Output. ADC conversion results are clocked out on the falling
edge of SCLK, MSB first. See Figure 1.
Serial Clock Input. SCLK drives the conversion process. DOUT is updated on the fall-
ing edge of SCLK. See Figures 2 and 3.
Exposed Pad (TDFN and FMAX only). Connect EP directly to a solid ground plane.
Devices do not operate unless EP is connected to ground!
