Overview
This device consists of two independent lowpower voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible. In addition, the device has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.
Applications
- Basic comparator
- Driving CMOS
- Driving TTL
- Low-frequency op-amp
- Low-frequency op-amp with boost
- Sensor amplifier
- Low-frequency op-amp with offset adjustment
- Single-supply zero-crossing detector
- Limiting comparator
- Zero-crossing detector for split-supply applications
- Crystal-controlled oscillator
- Comparator with negative reference
- Time delay generator
- Dual-decade high-frequency VCO
Key features
- Wide single supply voltage range or dual supplies +2V to +36V or ±1V to ±18V
- Very low supply current (0.4 mA) independent of supply voltage (1 mW/comparator at +5V)
- Low input bias current: 25 nA typ.
- Low input offset current: ±5 nA typ.
- Input common-mode voltage range includes negative rail
- Low output saturation voltage: 250 mV typ. (IO = 4 mA)
- Differential input voltage range equal to the supply voltage
- TTL, DTL, ECL, MOS, CMOS compatible outputs
- Automotive qualification
