Overview
The AS1976-T is an ultra-low current comparator from ams-OSRAM USA INC., packaged in a 5-pin SOT23. It operates on a single supply voltage ranging from 1.8V to 5.5V with a typical supply current of 200nA. The device features a push/pull output capable of sinking or sourcing up to 8mA, ensuring rail-to-rail output swings. Input common-mode voltage extends 200mV beyond the rails, and it includes built-in internal hysteresis of 3mV to prevent oscillation.
Feature Summary
- Ultra-low power consumption with 200nA supply current
- Push/pull output stage supporting up to 8mA load
- Input voltage range extends 200mV beyond supply rails
- Built-in 3mV internal hysteresis for stable switching
Applications
- Battery monitoring and management systems
- Mobile communication devices and PDAs
- Logic-level translation between 3V and 5V domains
- Threshold detectors and discriminators
Procurement Notes
Verify that the ordering suffix '-T' corresponds to the tape and reel delivery form as specified in the manufacturer's ordering information. Confirm the package type is 5-pin SOT23 and the output configuration matches the required push/pull functionality. Ensure compatibility with the specified operating temperature range of -40°C to +85°C for your application environment.
Selection Notes
Select the AS1976-T when a push/pull output is required for direct driving of loads without external pull-up resistors. Choose this component for applications demanding operation at voltages as low as 1.8V while maintaining low quiescent current. Consider the internal hysteresis for noise immunity in threshold detection circuits where additional external components are undesirable.
Part Context
The AS1976-T belongs to the AS1976/AS1977 family of ultra-low current comparators designed by austriamicrosystems AG (now ams-OSRAM). These devices are optimized for space-limited, low-power applications such as portable electronics and battery-powered systems. The family distinguishes itself through rail-to-rail input/output capabilities and minimal supply current consumption.
