Product details
Overview
LTC1992-1HMS8#PBF from Analog Devices (formerly Linear Technology) is a precision fixed-gain fully differential amplifier with 1× gain, rail-to-rail input/output, and independent VOCM control for level shifting in high-fidelity signal chains. It delivers ±0.3% max gain error over –40°C to 125°C, 3.5 ppm/°C gain tempco, and supports 2.7V single-supply or ±5V dual-supply operation in data acquisition systems.
For engineers reviewing the LTC1992-1HMS8#PBF datasheet, LTC1992-1HMS8#PBF pinout, LTC1992-1HMS8#PBF application, or LTC1992-1HMS8#PBF equivalent, key selection criteria include guaranteed H-grade temperature performance (–40°C to 125°C), ultrastable on-chip resistor network, CLOAD-stable operation up to 10,000 pF, and differential output phase balancing for multichannel ADC driver applications.
Technical Context
The LTC1992-1HMS8#PBF implements a fully differential architecture with separate internal common-mode feedback to minimize second-order harmonics and ensure exceptional output phase balance. Its VOCM pin sets output common-mode voltage independently of input common-mode range, enabling seamless interfacing between single-ended and differential domains.
It features precision trimmed on-chip resistors for fixed 1× differential gain, achieving ±0.1% typical gain error and 5 ppm long-term stability. Input common-mode range extends from (–VS – 0.1 V) to (+VS – 1.3 V), while rail-to-rail outputs source/sink ≥10 mA with <2.5 mV max DC offset voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain | Fixed 1× differential gain with ±0.3% max error over full temperature range - ensures accurate signal replication without external gain-setting components. |
| Supply Range | 2.7V single-supply to ±5V dual-supply - supports low-voltage portable designs and legacy ±5V industrial systems. |
| Output Swing | Rail-to-rail swing with ≥10 mA drive capability - maintains full dynamic range into 50 Ω loads or ADC inputs with minimal headroom loss. |
| Temp Range | –40°C to +125°C (H-grade) - qualified for under-hood automotive, industrial motor control, and high-reliability embedded systems. |
| Capacitive Load | Stable with up to 10,000 pF - eliminates need for isolation resistors when driving long traces, filters, or ADC input capacitance. |
| Input Offset | <2.5 mV max differential input offset voltage - preserves DC accuracy in precision sensor front-ends and weigh-scale amplifiers. |
| CMRR | ≥55 dB (min) at –40°C to 125°C - rejects common-mode noise in noisy industrial environments without degrading signal integrity. |
Pinout & Package
Package: 8-Lead Plastic MSOP (3 mm × 3 mm, 0.65 mm pitch), RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (–IN) | Inverting differential input | Accepts negative half of fully differential input signal; supports rail-to-rail common-mode range. |
| 2 (VOCM) | Output common-mode control | Sets output common-mode voltage independently; high-impedance (500 MΩ) input enables precise DC level translation. |
| 3 (+VS) | Positive supply rail | Connects to +2.7V to +5V (single) or +5V (dual); internal biasing optimized for low quiescent current. |
| 4 (+OUT) | Positive differential output | Delivers amplified positive-phase output; rail-to-rail swing supports direct connection to SAR or sigma-delta ADC inputs. |
| 5 (+IN) | Non-inverting differential input | Accepts positive half of fully differential input signal; matched impedance to Pin 1 ensures balanced noise rejection. |
| 6 (VMID) | Internal mid-supply reference | Provides stable 2.5 V (±60 mV) reference for single-supply biasing; not user-accessible but critical for internal common-mode feedback. |
| 7 (–VS) | Negative supply rail | Connects to GND (single) or –5V (dual); enables true bipolar signal handling and symmetric output swing. |
| 8 (–OUT) | Negative differential output | Delivers complementary negative-phase output; precisely balanced with Pin 4 for <–60 dB output common-mode imbalance. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential I/O architecture | Eliminates even-order distortion and improves PSRR/CMRR in high-resolution data converters. |
| On-chip precision gain resistors | Enables factory-trimmed 1× gain with ±0.3% max error - removes layout sensitivity and thermal drift from external resistors. |
| Independent VOCM control | Allows DC level shifting between mismatched domains (e.g., 0–5 V sensor to ±2.5 V ADC) without external op-amps. |
| CLOAD-stable operation | Drives 10,000 pF directly - simplifies anti-alias filter design and avoids stability-compromising series resistors. |
| H-grade temperature qualification | Guaranteed performance from –40°C to +125°C - suitable for engine control units, power inverters, and downhole instrumentation. |

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 (320 MHz vs. 3 MHz), higher supply current (20 mA vs. 1 mA), no integrated VOCM control - requires external feedback network. | Better suited for video or high-speed communication; less optimal for low-power, precision DC-coupled sensor interfaces. | Select AD8138ARZ only when >100 MHz small-signal bandwidth is required and VOCM flexibility is secondary. |
| LTC6409IUD#PBF | Higher gain-bandwidth (10 GHz), higher supply current (45 mA), fixed 2× gain - lacks 1× option and H-grade temperature rating. | Targeted at RF/IF signal chains; unsuitable for DC-accurate, low-power, extended-temperature applications. | Choose LTC6409IUD#PBF only for high-frequency (>100 MHz) AC-coupled applications where DC accuracy is irrelevant. |
Compared with AD8138ARZ and LTC6409IUD#PBF, the LTC1992-1HMS8#PBF uniquely combines H-grade temperature qualification, ultra-stable 1× gain, VOCM-controlled level shifting, and 1 mA quiescent current - making it the only choice for precision, low-power, extended-temperature differential signal conditioning.

FAQ
What is the maximum capacitive load the LTC1992-1HMS8#PBF can drive without instability?
The LTC1992-1HMS8#PBF is specified stable with capacitive loads up to 10,000 pF across its full operating temperature range. This eliminates the need for external isolation resistors when driving ADC input capacitance, anti-alias filters, or long PCB traces - a key advantage over many competing differential amplifiers that require careful compensation for loads >1000 pF.
Does the LTC1992-1HMS8#PBF support single-supply operation?
Yes, the LTC1992-1HMS8#PBF operates from a single 2.7V to 5V supply, with rail-to-rail input and output stages enabling full utilization of the supply range. The VOCM pin allows setting the output common-mode voltage anywhere between (–VS + 0.5 V) and (+VS – 1.3 V), facilitating seamless interfacing with single-supply ADCs such as the AD768x family.
What is the guaranteed gain error specification for the LTC1992-1HMS8#PBF over temperature?
The LTC1992-1HMS8#PBF guarantees ±0.3% maximum differential gain error over the full –40°C to +125°C operating temperature range. This specification is enabled by laser-trimmed on-chip thin-film resistors and applies to all H-grade variants, distinguishing it from C- and I-grade versions which are only guaranteed over narrower ranges.
How does the VOCM pin function in the LTC1992-1HMS8#PBF?
The VOCM pin in the LTC1992-1HMS8#PBF sets the output common-mode voltage independently of the input common-mode voltage. It presents a high-impedance (500 MΩ) input with ±2 pA bias current, allowing precise DC level translation - for example, converting a 0–5 V single-ended sensor output to a ±2.5 V differential signal for an ADC without additional active circuitry.
Is the LTC1992-1HMS8#PBF pin-compatible with other members of the LTC1992 family?
Yes, all LTC1992 variants - including LTC1992-1HMS8#PBF, LTC1992-2HMS8#PBF, and LTC1992-5HMS8#PBF - share identical 8-pin MSOP pinouts and package footprints. This allows designers to select gain options (1×, 2×, 5×, 10×) without modifying PCB layout, provided the application's bandwidth and noise requirements align with each variant's GBW and en specifications.
