Product details
Overview
LTC2051HVIMS10#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 1.5μVP-P (0.01Hz–10Hz) noise - enabling high-resolution thermocouple amplification and strain gauge measurement in industrial sensor interfaces.
For engineers reviewing the LTC2051HVIMS10#PBF datasheet, LTC2051HVIMS10#PBF pinout, LTC2051HVIMS10#PBF application, or LTC2051HVIMS10#PBF equivalent, key selection criteria include its ±5V extended supply capability (12V total), shutdown functionality, guaranteed –40°C to 85°C operation, and verified performance in low-side current sense and medical instrumentation circuits.
Technical Context
The LTC2051HVIMS10#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 RC filters and precision transimpedance stages.
It features independent shutdown control per amplifier (active-low SHDN A/B pins), rail-to-rail output stage capable of driving 2kΩ loads to both rails, and extended common-mode input range from V– to V+ – 1.3V - making it suitable for single-supply 3V systems and bipolar ±5V applications without level-shifting.
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 <0.3μV drift over 10°C ambient change, critical for unattended medical monitors. |
| Noise (0.01Hz–10Hz) | 1.5μVP-P - supports 20-bit ENOB in DC-coupled sensor interfaces with <100mV full-scale signals. |
| Supply Range | ±5V (12V total) - allows direct interface with legacy industrial ±5V signal chains and isolated power supplies. |
| Gain-Bandwidth | 3MHz - sufficient for anti-alias filtering at 100ksps sampling rates with unity-gain stability. |
| CMRR / PSRR | 130dB typical - rejects >1M:1 common-mode interference from motor drives or switching supplies. |
| Shutdown Current | ≤10μA per amplifier - enables battery-powered portable instruments with multi-second sleep cycles. |
Pinout & Package
Package: 10-lead plastic MSOP (3mm × 3mm), exposed pad connected to V– (pin 4). RoHS-compliant, lead-free #PBF finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Rail-to-rail capable; drives ≥2kΩ load to within 15mV of rails at ±5V supply. |
| 2 (–IN A) | Inverting input A | Low bias current (±150pA typ); sensitive to clock feedthrough if source impedance >10kΩ. |
| 3 (+IN A) | Non-inverting input A | Matches –IN A characteristics; ESD-sensitive (max 700V). |
| 4 (V–) | Negative supply | Reference for exposed thermal pad; must be low-impedance connection for thermal performance. |
| 5 (SHDN A) | Shutdown control A | Active-low; pulls output to high-Z when ≤V– + 0.5V; draws ≤5μA leakage. |
| 6 (V+) | Positive supply | Accepts up to +5.5V (or –5.5V on V–) for ±5V operation; PSRR >120dB. |
| 7 (OUT B) | Amplifier B output | Independent output; identical specs to OUT A; no crosstalk degradation in dual-channel use. |
| 8 (–IN B) | Inverting input B | Electrically isolated from –IN A; shares same autozero clock but no inter-channel coupling. |
| 9 (+IN B) | Non-inverting input B | Matched to +IN A; supports differential input configurations with matched external resistors. |
| 10 (SHDN B) | Shutdown control B | Independent of SHDN A; allows asymmetric power management in multi-stage signal chains. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-drift architecture | Autozeroing at 7.5kHz eliminates long-term drift and thermal hysteresis - essential for calibration-free field instruments. |
| Rail-to-rail output | Swings within 15mV of V+ and 2mV of V– into 2kΩ - maximizes dynamic range in 3.3V/5V microcontroller ADC interfaces. |
| Extended voltage rating | 12V total supply (±5V) - supports legacy industrial analog I/O modules without level-shifting components. |
| Dual independent shutdown | Per-amplifier SHDN pins enable granular power control - reduces idle current by >99% in portable data loggers. |
| High CMRR/PSRR | 130dB minimum - maintains accuracy in noisy PLC cabinets with shared ground returns and switching power supplies. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2051HVCMS10#PBF | Same architecture but rated for 0°C to 70°C only; lower cost; identical pinout and electrical specs at room temperature. | Suitable for commercial-grade consumer electronics where extended temperature qualification is unnecessary. | Select when operating environment stays within 0°C–70°C and cost sensitivity outweighs industrial temp grade assurance. |
| AD8628ARZ | Single zero-drift op amp (SO-8); 1μV max offset, 0.005μV/°C drift; no shutdown; 5.5V max supply. | Requires two devices for dual-channel use; lacks shutdown and ±5V capability - limits use in portable/battery systems. | Choose for ultra-low-drift single-channel needs where space permits SO-8 footprint and bipolar supply isn't required. |
Compared with LTC2051HVCMS10#PBF, the LTC2051HVIMS10#PBF adds guaranteed –40°C to 85°C operation and higher reliability screening, while AD8628ARZ offers superior drift performance but sacrifices dual-channel integration, shutdown, and supply flexibility.

FAQ
What is the maximum total supply voltage for LTC2051HVIMS10#PBF?
The LTC2051HVIMS10#PBF supports a maximum total supply voltage of 12V, enabling true ±5V operation (V+ = +5V, V– = –5V). This exceeds the standard LTC2051's 7V limit and is explicitly validated in the Absolute Maximum Ratings table for the HV variant. Operating beyond 12V risks permanent damage.
Does LTC2051HVIMS10#PBF require external capacitors for stability?
No, the LTC2051HVIMS10#PBF is unity-gain stable and does not require external compensation capacitors. Its internal architecture ensures stability with capacitive loads up to 100pF (per the Typical Performance Characteristics). However, a 0.1μF ceramic bypass capacitor between V+ and V–, placed within 5mm of the device, is mandatory for noise suppression and PSRR optimization.
How does the shutdown function behave on LTC2051HVIMS10#PBF?
Each amplifier in the LTC2051HVIMS10#PBF has an independent active-low shutdown pin (SHDN A on pin 5, SHDN B on pin 10). Pulling either pin ≤V– + 0.5V disables its respective amplifier, reducing supply current to ≤10μA and placing the output in high-impedance state. Both amplifiers remain functional when pins float or exceed V+ – 0.5V.
Can LTC2051HVIMS10#PBF drive a 10kΩ load rail-to-rail?
Yes - the LTC2051HVIMS10#PBF guarantees rail-to-rail output swing into 10kΩ loads, achieving V+ – 0.02V high and V– + 0.015V low at ±5V supply (per Electrical Characteristics table). Driving 2kΩ loads degrades swing to V+ – 0.06V / V– + 0.015V, still sufficient for most 12-bit+ ADC interfaces.
What is the input common-mode voltage range for LTC2051HVIMS10#PBF?
The LTC2051HVIMS10#PBF accepts input voltages from V– up to V+ – 1.3V across its full operating temperature range (–40°C to 85°C), as confirmed in the Electrical Characteristics table. This allows direct sensing of signals referenced to negative rails or ground in single-supply configurations without level-shifting circuitry.
