Product details

Overview

LTC1992-5HMS8#TRPBF from Analog Devices (formerly Linear Technology) is a fixed-gain, fully differential amplifier with precise 5× differential gain, rail-to-rail input/output operation, and independent VOCM-controlled output common-mode voltage. It operates from 2.7V single supply to ±5V dual supply, delivers ±10mA output current, and maintains ±0.3% max gain error over –40°C to 125°C for high-accuracy signal conditioning in precision data acquisition systems.

For engineers reviewing the LTC1992-5HMS8#TRPBF datasheet, LTC1992-5HMS8#TRPBF pinout, LTC1992-5HMS8#TRPBF application, or LTC1992-5HMS8#TRPBF equivalent, key selection criteria include guaranteed H-grade temperature range (–40°C to 125°C), 5× fixed gain with ±0.1% typical gain error, C_LOAD-stable operation up to 10,000pF, and differential driver capability for ADC front-ends requiring phase-balanced outputs.

Technical Context

The LTC1992-5HMS8#TRPBF implements a fully differential architecture with separate internal common-mode feedback path to ensure exceptional output phase balance and low second-order harmonics. Its VOCM pin sets output common-mode level independently of input common-mode, enabling seamless level shifting between single-ended and differential domains.

It features precision on-chip resistors for stable 5× gain, supports rail-to-rail inputs from (–V_S) to (+V_S – 1.3V), and exhibits <2.5mV max DC offset with 3.5ppm/°C gain temperature coefficient - critical for multichannel instrumentation where gain matching and thermal drift must be minimized.

Equivalent & Alternatives

The following parts are listed as comparable options for similar differential amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD8138ARZ	Higher bandwidth (350MHz vs 4MHz), higher supply current (20mA vs 1mA), no integrated VOCM control - requires external feedback network for gain setting	Better suited for high-speed video or RF IF applications; less optimal for low-power, precision DC-coupled systems	Select AD8138ARZ only when >100MHz small-signal bandwidth is required and power budget allows 20× higher quiescent current
LTC6409IUD#PBF	Higher gain-bandwidth (10GHz), lower noise (1.5nV/√Hz), but fixed 10× gain only - no 5× variant; requires external VOCM resistor divider	Targeted at RF/IF receiver chains with GHz bandwidth; not optimized for sub-10MHz precision instrumentation	Choose LTC6409IUD#PBF for RF sampling front-ends; LTC1992-5HMS8#TRPBF remains preferred for DC-accurate, low-power, fixed-5× gain needs

Compared with AD8138ARZ and LTC6409IUD#PBF, the LTC1992-5HMS8#TRPBF uniquely combines guaranteed 5× gain accuracy, ultra-low power (1mA), VOCM-integrated level shifting, and H-grade temperature reliability - making it the optimal choice for precision, thermally demanding, battery-aware measurement systems.

FAQ

What is the guaranteed gain accuracy of the LTC1992-5HMS8#TRPBF over its full operating temperature range?

The LTC1992-5HMS8#TRPBF guarantees ±0.3% maximum differential gain error from –40°C to 125°C. This specification is explicitly confirmed in the Electrical Characteristics table for all H-grade parts, ensuring predictable performance in automotive under-hood or industrial control cabinet deployments without recalibration.

Does the LTC1992-5HMS8#TRPBF require external resistors to set its 5× gain?

No, the LTC1992-5HMS8#TRPBF uses precision on-chip resistors to achieve its fixed 5× differential gain - eliminating external components, layout sensitivity, and resistor tolerance errors. This is a defining feature of the LTC1992-5 variant, unlike the base LTC1992 which is unconstrained and requires external feedback.

Can the LTC1992-5HMS8#TRPBF drive a 100Ω differential transmission line directly?

Yes, the LTC1992-5HMS8#TRPBF can drive a 100Ω differential load directly. With ±10mA minimum output current and rail-to-rail swing, it delivers up to 1V_PP into 100Ω (50Ω per side) while maintaining linearity and phase balance - verified in typical performance curves for C_LOAD = 100pF to 10,000pF.

What is the function of the VMID pin on the LTC1992-5HMS8#TRPBF?

The VMID pin on the LTC1992-5HMS8#TRPBF provides an internal mid-supply reference voltage (2.50V ±60mV at V_S = 5V). It is intended for biasing external circuitry or monitoring supply health, and must not be loaded beyond 1µA to avoid affecting accuracy - as specified in the Electrical Characteristics table.

Is the LTC1992-5HMS8#TRPBF pin-compatible with other members of the LTC1992 family?

Yes, the LTC1992-5HMS8#TRPBF shares identical 8-pin MSOP pinout and package dimensions with all LTC1992-x variants (e.g., LTC1992-1HMS8#TRPBF, LTC1992-10HMS8#TRPBF), enabling drop-in replacement for different gain requirements without PCB redesign - confirmed by the unified Pin Configuration diagram covering the entire family.
