Product details

Overview

LTC1992-10IMS8#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 delivers ±0.1% max gain error over –40°C to 85°C, supports supply voltages from 2.7V single-ended to ±5V dual, and sinks/sources ≥10mA output current - enabling high-fidelity single-ended-to-differential conversion in precision data acquisition systems.

For engineers reviewing the LTC1992-10IMS8#TRPBF datasheet, LTC1992-10IMS8#TRPBF pinout, LTC1992-10IMS8#TRPBF application, or LTC1992-10IMS8#TRPBF equivalent, key selection criteria include guaranteed gain accuracy across temperature, C_LOAD-stable operation up to 10,000pF, low 1mA max supply current, and MSOP-8 packaging for space-constrained analog front-ends.

Technical Context

The LTC1992-10IMS8#TRPBF implements a fully differential architecture with separate internal common-mode feedback, ensuring <–85dB output phase imbalance and reduced second-order harmonics. Its precision on-chip resistor network fixes differential gain at exactly 10 V/V with ±0.1% max error over full temperature range.

It features a dedicated VOCM pin that sets output common-mode level independently of input common-mode voltage - enabling seamless level shifting between disparate supply domains. Input common-mode range extends from (–V_S – 0.1V) to (+V_S – 1.3V), supporting rail-to-rail operation across all supported supply configurations.

Key Specifications

Parameter	Value and Actual Design Meaning
Fixed Differential Gain	10 V/V, ±0.1% max error from –40°C to 85°C - enables accurate signal scaling without external gain-setting resistors
Supply Voltage Range	2.7V to 11V total (single-supply) or ±5V (dual-supply) - supports low-voltage battery-powered and industrial ±5V systems
Output Current Drive	≥10mA sourcing/sinking per output - drives heavy capacitive loads and 50Ω/100Ω differential transmission lines directly
Capacitive Load Stability	Stable with C_LOAD ≤ 10,000pF - eliminates need for isolation resistors in ADC driver applications
Input Offset Voltage	±2.5mV max (input-referred) - preserves DC accuracy in precision sensor interfaces and instrumentation amplifiers
Supply Current	1.0mA max at 2.7V to 5V - enables low-power operation in portable and always-on monitoring systems
Gain Temperature Coefficient	3.5ppm/°C - ensures stable gain calibration over wide ambient temperature swings

Pinout & Package

Package: 8-Lead Plastic MSOP (3mm × 3mm, 0.65mm pitch), –40°C to 85°C operating temperature range.

Pin/Terminal	Circuit Role	Design Meaning
1 (–IN)	Inverting differential input	Accepts negative half of fully differential input signal; rail-to-rail common-mode range supports direct connection to sensors or DAC outputs
2 (VOCM)	Output common-mode control	Sets average of +OUT and –OUT voltages independently - enables level translation between 0–2.5V and ±2.5V domains
3 (+VS)	Positive supply	Connects to single +2.7V to +5V rail or positive side of ±5V dual supply; decoupling required near pin
4 (+OUT)	Positive differential output	Delivers amplified, phase-matched output; rail-to-rail swing allows full utilization of downstream ADC input range
5 (+IN)	Non-inverting differential input	Accepts positive half of fully differential input; matched impedance to Pin 1 ensures balanced noise rejection
6 (VMID)	Internal mid-supply reference	Provides buffered 2.5V (at 5V supply) or ~V_S/2 - usable as bias reference for external circuitry
7 (–VS)	Negative supply	Ground for single-supply operation or –5V for dual-supply; must be connected even in single-ended configurations
8 (–OUT)	Negative differential output	Complementary to +OUT; maintains tight amplitude/phase matching (<–85dB balance) critical for high-SFDR applications

Key Features

Feature	Design Value
Fully differential I/O architecture	Rejects common-mode noise and power supply ripple; enables >90dB CMRR in properly laid-out PCBs
Precision on-chip gain resistors	Eliminates external resistor matching errors and thermal drift - achieves ±0.1% gain accuracy without trimming
Independent VOCM control	Decouples output DC level from input stage - simplifies interfacing between mixed-supply subsystems (e.g., 3.3V MCU to ±5V ADC)
Rail-to-rail input/output swing	Maximizes dynamic range utilization in low-voltage systems; supports 0–2.7V input and 0–2.7V output with 2.7V supply
C_LOAD-stable operation up to 10,000pF	Drives long traces, unbuffered ADC inputs, and EMI filters without oscillation - removes need for output series resistors

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
AD8138ARZ	Higher bandwidth (350MHz vs 4MHz), higher supply current (20mA), no integrated VOCM control - requires external feedback network for gain setting	Better suited for high-frequency video or RF IF applications; less suitable for low-power, precision DC-coupled systems	Select AD8138ARZ only when >100MHz small-signal bandwidth is required and power budget allows 20mA per channel
THS4561IRGET	Lower supply current (1.2mA typ), lower noise (2.3nV/√Hz), but ±0.5% gain error and no factory-trimmed resistors - requires external gain resistors	Ideal for ultra-low-noise, battery-powered instrumentation where moderate gain accuracy suffices	Choose THS4561IRGET when optimizing for lowest possible noise floor and can accept ±0.5% gain tolerance with external resistor matching

Compared with AD8138ARZ and THS4561IRGET, the LTC1992-10IMS8#TRPBF uniquely combines factory-trimmed 10× gain accuracy, ultralow 1mA supply current, and integrated VOCM control - making it optimal for space- and power-constrained precision analog front-ends where gain stability and ease of use are prioritized over raw bandwidth.

FAQ

What is the guaranteed gain accuracy of the LTC1992-10IMS8#TRPBF over temperature?

The LTC1992-10IMS8#TRPBF guarantees ±0.1% maximum differential gain error over its full operating temperature range of –40°C to 85°C. This specification is achieved via laser-trimmed on-chip resistors and is explicitly validated per the manufacturer's datasheet for the IMS8 grade part - eliminating the need for system-level gain calibration in most precision applications.

Can the LTC1992-10IMS8#TRPBF operate from a single 3.3V supply?

Yes, the LTC1992-10IMS8#TRPBF operates from a single 2.7V to 11V supply, making 3.3V fully supported. At 3.3V, its rail-to-rail inputs accept common-mode voltages from 0V to 2.0V, and outputs swing within 100mV of each rail while delivering ≥10mA drive capability - ideal for interfacing with 3.3V ADCs and microcontrollers.

Does the LTC1992-10IMS8#TRPBF require external gain-setting resistors?

No. The LTC1992-10IMS8#TRPBF integrates precision laser-trimmed resistors to fix its differential gain at exactly 10 V/V. No external resistors are needed for gain configuration - reducing component count, board area, and potential errors from resistor mismatch or thermal drift.

How does the VOCM pin function in the LTC1992-10IMS8#TRPBF?

The VOCM pin on the LTC1992-10IMS8#TRPBF sets the average voltage of the +OUT and –OUT pins independently of the input common-mode level. Applying a voltage (e.g., 1.65V) to VOCM forces (+OUT + –OUT)/2 = 1.65V - enabling level shifting between incompatible supply domains without affecting gain or signal integrity.

Is the LTC1992-10IMS8#TRPBF stable when driving large capacitive loads?

Yes. The LTC1992-10IMS8#TRPBF is specified as stable for capacitive loads up to 10,000pF across its full operating range. This eliminates the need for series output resistors typically required with other op-amps, simplifying layout and preserving signal fidelity in ADC driver and filter interface applications.
