ZoomingADC for sensing data acquisition

DATASHEET

Note

The bottom pin is internally connected to VSS. It should also be connected to

VSS on PCB to reduce noise and improve thermal behavior.

Function

Differential sensor input in conjunction with AC5

Differential sensor input in conjunction with AC4

2.4V to 5.5V power supply

Chip Ground

Conversion complete flag.

Digital output sensor drive (VBATT or VSS)

VREF input in optional operating mode

I2C address bit 1. MSB address bits are fuse programmed.

Digital output sensor drive (VBATT or VSS)

VREF output in optional operating mode

I2C address bit 0. Msb address bits are fuse programmed.

I2C data

I2C clock. Up to 400KHz.

Charge pump output. Raises analog switch supply above VBATT if VBATT supply is

too low. Recommended range for capacitor is 1nF to 10 nF. Connect the

capacitor to ground.
