Description

The LM319AMX is a high‑speed voltage comparator in an 8‑pin AMX surface‑mount package. It compares two analog inputs and provides a digital output indicating which input is higher, making it useful for fast threshold detection, zero‑crossing, PWM comparators, and other analog–digital interfacing tasks. The AMX suffix denotes TI’s 8‑pin SMT variant. Key points: it can operate from a single or dual supply (depending on version) and is designed for fast response; the exact input common‑mode range, output behavior, and supply limits depend on the specific device and temperature. For precise electrical specs and recommended circuits, consult the LM319AMX datasheet.

Features

LM319AMX features (concise):
- High-speed voltage comparator
- Open-collector outputs (sinks current; use pull-up resistor; enables wired-AND)
- Wide single-supply range (approx 4.5 V to 30 V)
- Input common-mode range includes ground
- Low offset voltage and fast propagation delay (suitable for fast switching)
- Output can interface with TTL/CMOS via pull-up
- Industrial temperature range (-40°C to +125°C)
- 8-pin AMX package (and related DIP/SOP variants)
Note: For exact values (propagation delay, current sinks, precise voltage ranges) please consult the specific LM319AMX datasheet.

Package

SOIC-8 (8-pin small-outline) – the LM319AMX variant is the surface-mount SOIC-8 package.

Pinout

- Pin count: 8 pins (DIP-8/SOIC-8)
- Function: High-speed single-channel voltage comparator (open-collector output; requires a pull-up resistor). It compares two input voltages and outputs a logic-level signal accordingly.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- Company type: An American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

LM319AMX is a high-speed voltage comparator. Applications include fast threshold/zero-cross detection, PWM/motor-control front ends, ADC input comparators and sample/hold timing, peak/valley and envelope detectors, window/hysteresis detectors, alarm/trip sensing, and line receivers in data communications.
