概述

Description

LM193H isn’t a widely standardized part number. It’s likely a manufacturer-specific variant suffix for an LM193 family voltage comparator. To give you a precise intro, I need the exact manufacturer or datasheet (or confirm if you mean LM193/LM193H-grade from a particular vendor). If you share that, I’ll provide a concise, feature-focused summary (typical items: purpose, output type, supply range, input common-mode range, and applications).

Features

Here are the typical features of the LM193H (dual general‑purpose operational amplifier, hermetic variant):
- Dual operational amplifiers in one package
- Hermetically sealed (military/aerospace style) LM193H version
- Wide supply voltage range; suitable for single‑ or dual‑supply operation
- Input common‑mode range includes the negative rail
- Output can swing close to the rails under light loading
- Unity‑gain stable with easy closed‑loop configurations
- Low input offset voltage and low drift; low input bias current
- Moderate to low noise and distortion suitable for instrumentation
- Stable over a broad temperature range (typical MIL‑SPEC range for H variant)
- Applications: instrumentation, control circuits, sensor conditioning, audio, and general analog signal processing
Note: exact electrical specs (offset, bias, bandwidth, slew rate, supply limits) vary by lot and package; consult the latest datasheet for precise numbers.

Package

LM193H denotes the hermetic version. It is typically in an 8-pin metal can package (TO-5/TO-99 family). Some vendors may offer alternative packages; always confirm from the manufacturer’s datasheet.

Pinout

- Pin count: 8 pins (DIP-8/SO-8).
- Function: Dual voltage comparator (two independent comparators with open-collector outputs). Each comparator compares its non-inverting and inverting inputs and pulls its output low when the + input is greater than the − input, otherwise is high-impedance.

Manufacturer

- Manufacturer: National Semiconductor (historical); now part of Texas Instruments.
- Company type: American semiconductor company that designs and manufactures analog and mixed-signal integrated circuits.

Application

LM193H is a dual precision operational amplifier. Common applications:
- Precision instrumentation and sensor signal conditioning
- Active filters (low/high/band-pass)
- DC servo circuits and integrators
- Audio preamplifiers and general analog signal amplification
- Voltage followers and differential amplifiers in data acquisition and control systems

Equivalent

LM193H is a dual comparator. Direct equivalents you can use are from the LM393/LM2903 family:
- LM393 (and LM393N)
- LM2903 (and LM2903N)
These are the same-logic, dual open-collector comparators from TI/On Semiconductor/ST/Fairchild, with cross-refs from NTE as well. Always verify pinout and supply ranges for your package.
