Analog Devices Inc. LTC1992-10HMS8#TRPBF

Overview

LTC1992-10HMS8#TRPBF from Analog Devices (formerly Linear Technology) is a fixed-gain, fully differential amplifier with precise 10× 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 LTC1992-10HMS8#TRPBF datasheet, LTC1992-10HMS8#TRPBF pinout, LTC1992-10HMS8#TRPBF application, or LTC1992-10HMS8#TRPBF equivalent, key selection criteria include guaranteed 10× gain accuracy across temperature, 125°C extended operating range, MSOP-8 package compatibility with space-constrained layouts, and VOCM-driven level-shifting capability for ADC driver interfaces.

Technical Context

The LTC1992-10HMS8#TRPBF implements a fully differential architecture with on-chip precision resistors setting its fixed 10× differential gain, eliminating external resistor matching errors. Its separate internal common-mode feedback path ensures <–60dB output balance and reduced second-order harmonics, critical for multichannel synchronization.

It features a dedicated VOCM pin that sets output common-mode voltage independently of input common-mode range-enabling seamless interfacing between single-ended sources and differential-input ADCs. Input common-mode range extends from (–VS – 0.1V) to (+VS – 1.3V), supporting rail-to-rail operation under all supply configurations.

FAQ

What is the maximum guaranteed gain error for LTC1992-10HMS8#TRPBF over temperature?

The LTC1992-10HMS8#TRPBF guarantees ±0.3% maximum differential gain error across its full operating temperature range of –40°C to +125°C. This specification is achieved via on-chip laser-trimmed thin-film resistors and applies to all H-grade devices, making it suitable for uncalibrated precision applications in harsh thermal environments.

Does LTC1992-10HMS8#TRPBF require external gain-setting resistors?

No, the LTC1992-10HMS8#TRPBF does not require external gain-setting resistors. It integrates precision laser-trimmed resistors to deliver a fixed 10× differential gain. This eliminates resistor matching errors, thermal drift mismatches, and board area typically needed for discrete gain networks-reducing design complexity and improving long-term stability.

Can LTC1992-10HMS8#TRPBF operate from a single 3.3V supply?

Yes, the LTC1992-10HMS8#TRPBF is fully specified for single-supply operation from +2.7V to +5V. With a 3.3V supply, it delivers rail-to-rail output swing (typically 0.02V to 3.28V per output), supports input common-mode voltages from –0.1V to 2.0V, and maintains ±2.5mV max input offset-making it ideal for modern low-voltage data acquisition systems.

What is the function of the VMID pin on LTC1992-10HMS8#TRPBF?

VMID on the LTC1992-10HMS8#TRPBF provides a buffered mid-supply reference voltage (2.44V–2.57V at 25°C) derived internally from the supply rails. It serves as a stable bias point for single-supply configurations-e.g., when driving ADCs requiring VREF/2 common-mode-and can be used to terminate unused inputs or set common-mode levels without external dividers.

Is LTC1992-10HMS8#TRPBF stable when driving large capacitive loads?

Yes, the LTC1992-10HMS8#TRPBF is explicitly characterized for stability with capacitive loads up to 10,000pF. This allows direct connection to high-input-capacitance ADCs (e.g., successive-approximation or pipeline types), long PCB traces, or filtering networks without external isolation resistors-preserving phase margin and step response fidelity in precision sampling systems.
