Product details
Overview
LTC2051HVIMS8#PBF from Analog Devices (formerly Linear Technology) is a dual zero-drift operational amplifier in an 8-lead MSOP package, designed for precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3μV, max offset drift of 30nV/°C, rail-to-rail output swing, and 1.5μVP-P (0.01Hz–10Hz) noise - enabling high-resolution thermocouple amplification and strain gauge measurement in industrial sensor interfaces.
For engineers reviewing the LTC2051HVIMS8#PBF datasheet, LTC2051HVIMS8#PBF pinout, LTC2051HVIMS8#PBF application, or LTC2051HVIMS8#PBF equivalent, key selection criteria include its ±5V supply capability, –40°C to 85°C operating range, HV-grade 12V total supply voltage rating, and verified performance in low-side current sense and medical instrumentation circuits where long-term DC stability is critical.
Technical Context
The LTC2051HVIMS8#PBF employs autozeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves near-zero DC error while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate - supporting stable closed-loop operation in active filters and precision transimpedance stages.
It features extended common-mode input range (V– to V+ – 1.3V), 130dB typical PSRR and CMRR, and rail-to-rail output drive into 2kΩ loads. Shutdown functionality is not present in the MS8 package variant, distinguishing it from the 10-lead MSOP version.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3μV - enables sub-10μV system-level DC error in 24-bit DAQ front-ends without calibration. |
| Offset Drift | Max ±30nV/°C - ensures <±0.5μV total drift over 85°C temperature span, critical for unattended field instrumentation. |
| Noise (0.01Hz–10Hz) | 1.5μVP-P - supports resolution better than 20-bit ENOB in DC-coupled sensor amplifiers. |
| Supply Range | 2.7V single or ±5V dual - compatible with legacy industrial rails and modern low-voltage systems without level-shifting. |
| Gain-Bandwidth Product | 3MHz - sufficient for anti-alias filtering at 100ksps sampling and stable unity-gain buffer operation. |
| CMRR / PSRR | 130dB typ - rejects >1M:1 common-mode or supply ripple, essential in noisy PLC and motor-control environments. |
| Operating Temp | –40°C to +85°C - qualified for industrial control cabinets and outdoor sensor nodes without derating. |
Pinout & Package
Package: 8-lead MSOP (MS8), 3mm × 3mm × 0.8mm body, exposed pad connected to V– (pin 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Rail-to-rail capable; drives ≥2kΩ load to within 60mV of either rail at 5V supply. |
| 2 (–IN A) | Inverting input A | Low bias current (±90pA typ); sensitive to PCB leakage and ESD - requires guard ring layout. |
| 3 (+IN A) | Non-inverting input A | Matches –IN A in offset and drift; input common-mode extends to V– and up to V+ – 1.3V. |
| 4 (V–) | Negative supply | Reference for exposed thermal pad; must be low-impedance connection for thermal and noise performance. |
| 5 (V+) | Positive supply | Accepts 2.7V to 5.5V single or ±5V dual; PSRR >120dB minimizes supply noise coupling. |
| 6 (OUT B) | Amplifier B output | Independent output stage; no crosstalk specification given - layout isolation recommended. |
| 7 (–IN B) | Inverting input B | Electrically identical to –IN A; usable for differential pair or independent channel applications. |
| 8 (+IN B) | Non-inverting input B | Matches +IN A; supports dual-channel sensor conditioning (e.g., bridge + reference). |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift autozeroing | Continuous correction at 7.5kHz eliminates thermal and time-dependent DC errors without external calibration. |
| Rail-to-rail output | Swings within 60mV of V+ and 15mV of V– into 2kΩ - maximizes dynamic range in single-supply data acquisition. |
| High DC precision | 130dB CMRR/PSRR and 140dB open-loop gain enable <0.1ppm linearity error in precision gain stages. |
| Low 1/f noise | 1.5μVP-P (0.01Hz–10Hz) supports stable DC measurements in electronic scales and medical ECG front-ends. |
| HV supply rating | 12V total supply (V+ to V–) allows ±5V operation with 1V headroom - compatible with standard industrial bipolar rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051IMS8#PBF | Same package and pinout; rated for 3V/5V only (7V max supply), not ±5V; 0°C to 70°C temp range. | Not suitable for ±5V industrial systems or extended temperature deployments. | Select only for cost-sensitive commercial-grade designs with ≤70°C ambient and single-rail operation. |
| AD8628ARMZ | Single zero-drift op amp (not dual); 2.7V–5.5V supply; 1.5μVP-P noise; 6V max supply; –40°C to 125°C. | Requires two devices for dual-channel use; lacks HV rating for ±5V operation. | Choose when single-channel function suffices and wider temperature range (–40°C to 125°C) is mandatory. |
Compared with LTC2051IMS8#PBF, the LTC2051HVIMS8#PBF adds ±5V compatibility and extended temperature qualification; versus AD8628ARMZ, it provides integrated dual-channel functionality and higher supply voltage margin - reducing component count and layout complexity in space-constrained industrial DAQ modules.

FAQ
What is the maximum supply voltage rating for the LTC2051HVIMS8#PBF?
The LTC2051HVIMS8#PBF has a total supply voltage (V+ to V–) rating of 12V, enabling reliable operation with ±5V supplies (10V total) plus 2V of margin. This HV designation distinguishes it from standard LTC2051 variants rated for 7V max, making it suitable for industrial systems with rail tolerances or transient overvoltage conditions.
Does the LTC2051HVIMS8#PBF include a shutdown pin?
No, the LTC2051HVIMS8#PBF in the 8-lead MSOP (MS8) package does not include a shutdown pin. Shutdown functionality is only available on the 10-lead MSOP (MS10) variant (e.g., LTC2051HVIMS10). The MS8 package provides dual op amp functionality in minimal area without power-management features.
What is the input common-mode voltage range for the LTC2051HVIMS8#PBF?
The LTC2051HVIMS8#PBF supports an extended input common-mode range from the negative supply rail (V–) up to V+ – 1.3V. At ±5V supply, this spans –5V to +3.7V - allowing direct interfacing with sensors whose outputs swing near ground or above mid-rail without level-shifting circuitry.
How does the LTC2051HVIMS8#PBF achieve its low offset drift?
The LTC2051HVIMS8#PBF uses continuous autozeroing with a 7.5kHz internal clock to sample and nullify input offset voltage and its temperature-induced drift in real time. This chopper-stabilized architecture achieves typical drift of 10nV/°C and max 30nV/°C - eliminating the need for periodic system calibration in long-duration measurements.
Is the exposed pad on the LTC2051HVIMS8#PBF package electrically connected?
Yes, the exposed thermal pad on the bottom of the LTC2051HVIMS8#PBF MS8 package is internally connected to the V– pin (pin 4). It must be soldered to a PCB copper pour tied to the negative supply plane to ensure proper thermal dissipation and low-noise performance - floating or isolated pads degrade both thermal resistance and PSRR.
