Maximum Operating Temperature: +85°C

Input Current: 160 uA

Input Voltage Range: 2.8 V to 16.5 V

Operating Supply Current: 160 uA

Operating Supply Voltage: 2.8 V to 16.5 V

Output Voltage Range: -5 V to -1.6 V

Product Features:

High Precision: With a maximum error of ±0.2 mV ± 0.3% of reading under sine wave input, it can measure a wide range of input waveforms with high precision, including variable duty cycle pulses and sine waves controlled by triac.

Wide Input Range: 200 mV full-scale input range, with the ability to achieve larger inputs using an input attenuator.

Low Power Consumption Design: Power supply current is only 160 μA (maximum), with standby current less than 30 μA in shutdown mode, making it suitable for battery-powered devices.

High Input Impedance: 10^12^ Ω, with low input bias current of 25 pA (maximum), allowing direct connection to high-impedance attenuators or analogue-to-digital converters.

Wide power supply voltage range: ±2.5 V to ±16.5 V.

No external adjustment required: Achieves specified accuracy without external trimming.

Package type: 8-pin SOIC package, suitable for surface mount.

Operating temperature range: 0°C to 70°C.
