Description
Voltage output. The output voltage is referenced to GND.
The overall voltage gain is 50, i.e.,
VOUT = 50 x VSENSE where VSENSE = VS+ - VS-
Ground and substrate connection of device
High impedence negative sense voltage input
Positive sense input. Also acts as power supply pin to ZXCT1023

These are stress ratings only. Operation outside the absolute maximum ratings may cause device failure. Operation at the absolute
maximum rating for extended periods may reduce device reliability.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken
when handling and transporting these devices.
Notes:
1. Measured with respect to GND pin
2. Subject to absolute maximum VSENSE not being exceeded.
3. VSENSE is defined as the voltage difference across the sense resistor, RS.
4. The usable VSENSE range is limited by the output voltage range; and as such will be reduced at lower VS+ values.
