Overview
The LM319AMX is a high-speed dual analog comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It features an open-collector output configuration capable of driving up to 25mA. The device operates on a single supply voltage ranging from 5V to 36V or dual supplies from ±2.5V to ±18V. Key electrical parameters include a typical response time of 80ns at ±15V, a maximum input bias current of 1μA, and a maximum input offset voltage of 8mV. The unit supports commercial operating temperatures between 0°C and 70°C.
Feature Summary
- High-speed differential comparison with rapid switching characteristics suitable for fast signal processing.
- Open-collector outputs allow direct interfacing with various logic families including TTL, DTL, and RTL.
- Wide single-supply voltage range enables flexible integration into diverse power supply architectures.
Applications
- Fast A/D converter interface circuits
- Waveform generation and shaping systems
