Product details
Overview
LTC2051HVCMS10#PBF from Analog Devices (formerly Linear Technology) is a dual zero-drift operational amplifier in a 10-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 operates from ±5V supplies with 750μA per amplifier supply current. It is used in thermocouple amplifiers, strain gauge interfaces, and high-resolution data acquisition systems where long-term DC stability is critical.
For engineers reviewing the LTC2051HVCMS10#PBF datasheet, LTC2051HVCMS10#PBF pinout, LTC2051HVCMS10#PBF application, or LTC2051HVCMS10#PBF equivalent, key selection criteria include guaranteed 0°C to 70°C operation, HV-rated ±5V supply support, shutdown functionality, low 1.5μVP-P (0.01Hz–10Hz) noise, and confirmed 10-lead MSOP pin mapping with SHDN pins.
Technical Context
The LTC2051HVCMS10#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.
It features two independent shutdown pins (SHDN A and SHDN B), enabling per-amplifier power control. Input common-mode range extends from V– to within 1.3V of V+, and output drives 2kΩ loads rail-to-rail - critical for single-supply sensor front-ends requiring full dynamic range utilization.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max ±3μV - enables sub-10μV system-level DC error in precision bridge or thermocouple circuits without calibration. |
| Offset Drift | Max ±30nV/°C - ensures <1μV total drift over 0°C–70°C operating range, eliminating thermal nulling circuitry. |
| Noise (0.01Hz–10Hz) | 1.5μVP-P - supports 18-bit+ resolution in low-frequency data acquisition without external filtering. |
| Supply Range | ±5V (12V total) - supports bipolar sensor interfaces and legacy industrial signal chains without level-shifting. |
| Gain-Bandwidth | 3MHz - sufficient for anti-aliasing filters up to ~300kHz and closed-loop gains ≤300 in precision instrumentation. |
| CMRR / PSRR | 130dB typical - rejects >1M:1 common-mode or supply noise, essential for noisy industrial environments. |
| Shutdown Current | ≤10μA per amplifier - allows power-gating unused channels in battery-powered portable instruments. |
Pinout & Package
Package: 10-lead plastic MSOP (3mm × 3mm), exposed pad connected to V–. Pin pitch: 0.5mm. RoHS-compliant lead-free finish (#PBF).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives ≥2kΩ load to both rails. |
| 2 | –IN A | Inverting input A - high-impedance node (<150pA bias current at 25°C) for precision feedback networks. |
| 3 | +IN A | Non-inverting input A - matched to –IN A for optimal CMRR; ESD-sensitive (max 700V). |
| 4 | V– | Negative supply - also connects to exposed thermal pad; must be low-impedance for noise and thermal performance. |
| 5 | SHDN A | Active-low shutdown control for Amplifier A - pulls low to reduce current to ≤10μA; floats high for normal operation. |
| 6 | V+ | Positive supply - accepts +5V (or +3V); total supply voltage limited to 12V (V+ to V–). |
| 7 | OUT B | Amplifier B output - electrically identical to OUT A; independent channel for dual-sensor or differential pair use. |
| 8 | –IN B | Inverting input B - fully isolated from Channel A; enables true dual-channel signal conditioning on one die. |
| 9 | +IN B | Non-inverting input B - matched pair with –IN B; supports independent gain/offset tuning per channel. |
| 10 | SHDN B | Active-low shutdown control for Amplifier B - independent of SHDN A, allowing asymmetric power management. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift autozeroing | Continuous correction at 7.5kHz eliminates thermal and time-dependent offset drift - no manual nulling required in field-deployed equipment. |
| Rail-to-rail output | Swings within 15mV of rails into 2kΩ - maximizes ADC dynamic range in 3.3V or 5V systems without external level-shifting. |
| Dual independent shutdown | Per-channel SHDN pins enable selective power-down - reduces system standby current by >99% when only one amplifier is active. |
| High-voltage supply rating | 12V total supply (±5V) - supports legacy industrial sensors and transducers requiring bipolar excitation or signal swing. |
| Low 0.01Hz–10Hz noise | 1.5μVP-P - enables direct digitization of microvolt-level thermocouple outputs with minimal oversampling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051CMS10#PBF | Same pinout and architecture, but rated for 0°C to 70°C only and lacks ±5V supply support (max 7V total). | Suitable for commercial-grade, single-supply (3V/5V) applications where HV operation and extended temp are not required. | Select LTC2051CMS10#PBF only if system operates strictly within 0°C–70°C and uses ≤5V single supply or ±3.5V max. |
| LTC2051HVCS8#PBF | Same HV rating and specs, but in 8-lead SOIC package - no shutdown pins, larger footprint, lower thermal performance (θJA = 250°C/W vs 190°C/W). | Preferred for through-hole prototyping or legacy SOIC-based designs where space and thermal constraints are less critical. | Choose LTC2051HVCS8#PBF only when board layout prohibits MSOP or shutdown functionality is unnecessary. |
Compared with LTC2051CMS10#PBF and LTC2051HVCS8#PBF, the LTC2051HVCMS10#PBF uniquely combines ±5V operation, 10-lead MSOP compactness, dual shutdown capability, and 0°C–70°C qualification - making it optimal for space-constrained, bipolar-sensor industrial modules requiring flexible power management.

FAQ
What is the maximum supply voltage rating for the LTC2051HVCMS10#PBF?
The LTC2051HVCMS10#PBF supports a total supply voltage (V+ to V–) of up to 12V, enabling ±5V operation. This HV rating distinguishes it from standard LTC2051 variants limited to 7V. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2051HVCMS10#PBF include shutdown functionality?
Yes, the LTC2051HVCMS10#PBF includes two independent active-low shutdown pins (SHDN A and SHDN B, Pins 5 and 10). Pulling either pin low reduces its respective amplifier's supply current to ≤10μA while placing the output in high-impedance state - a feature absent in 8-lead versions like LTC2051HVCMS8#PBF.
What is the input offset voltage specification for the LTC2051HVCMS10#PBF?
The LTC2051HVCMS10#PBF has a maximum input offset voltage of ±3μV at 25°C, with typical performance of ±0.5μV. This value is guaranteed over the 0°C to 70°C operating range and is achieved via continuous autozeroing - critical for applications demanding sub-microvolt DC accuracy.
Can the LTC2051HVCMS10#PBF drive capacitive loads?
The LTC2051HVCMS10#PBF is not unity-gain stable with large capacitive loads. Driving >100pF directly may cause peaking or oscillation. For capacitive loads (e.g., ADC input capacitance), use an isolation resistor (≥100Ω) between output and capacitor, or add a small series resistor (10–50Ω) with a feedback capacitor to maintain stability per Layout Guidelines in the datasheet.
Is the exposed pad on the LTC2051HVCMS10#PBF internally connected?
Yes, the exposed pad on the bottom of the LTC2051HVCMS10#PBF MSOP package is internally connected to V– (Pin 4). It must be soldered to a PCB copper pour tied to the negative supply plane to ensure proper thermal dissipation (θJA = 190°C/W) and low-noise performance - floating or misconnected pads degrade PSRR and increase thermal resistance.
