Product details
Overview
LTC2052HVIGN#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in a 16-lead SSOP package, designed for precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3μV, max offset drift of 30nV/°C, 1.5μVP-P (0.01Hz–10Hz) input-referred noise, rail-to-rail output swing, and operates from ±5V supplies with total supply voltage up to 12V - ideal for thermocouple amplification and high-resolution data acquisition systems.
For engineers reviewing the LTC2052HVIGN#PBF datasheet, LTC2052HVIGN#PBF pinout, LTC2052HVIGN#PBF application, or LTC2052HVIGN#PBF equivalent, key selection criteria include guaranteed 12V total supply rating, –40°C to 85°C operating temperature range, 130dB CMRR/PSRR, shutdown capability, and compatibility with low-source-impedance sensor interfaces requiring sub-microvolt DC accuracy.
Technical Context
The LTC2052HVIGN#PBF employs autozeroing architecture with a 7.5kHz internal sampling clock to continuously correct input offset and drift. Its dual-stage chopper-stabilized design achieves near-zero DC errors while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate.
It features independent shutdown control per amplifier pair (pins 9 and 10), 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 - enabling direct interfacing with bridge sensors and current-sense resistors without level-shifting.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives ≥2kΩ load to either supply |
| 2 | –IN A | Inverting input of Amp A - high-impedance node; sensitive to PCB leakage and ESD |

|---|---|
Use Scenario: Amplifying microvolt-level Seebeck voltages from K-type thermocouples across –200°C to +1350°C, with cold-junction compensation. IC Role / Device Role / Timing Role: Primary DC-coupled instrumentation amplifier stage; provides gain, offset correction, and noise filtering before ADC digitization. Use Value: 3μV max offset ensures <0.1°C absolute error at 0°C reference; 30nV/°C drift limits thermal drift-induced error to <0.05°C over 85°C ambient range. | Use Scenario: Reading Wheatstone bridge outputs from metal foil strain gauges in load cells and pressure transducers. IC Role / Device Role / Timing Role: First-stage differential amplifier with programmable gain; rejects bridge common-mode voltage and lead resistance effects.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052IGN#PBF | Same quad zero-drift architecture but rated for 7V total supply (±3.5V); lacks HV designation | Not suitable for ±5V systems or 12V total supply rails; lower voltage headroom limits sensor excitation flexibility | Select only if operating strictly within 0°C–70°C and using ≤±3.5V supplies |
| AD8628ARUZ | Single-supply-only (2.7V–5.5V), no shutdown, 1.5μVP-P noise, but only 2MHz GBW and no HV rating | Cannot replace LTC2052HVIGN#PBF in bipolar supply or multi-amp channel-count applications | Consider only for space-constrained single-channel 3.3V systems where shutdown and ±5V operation are unnecessary |
Compared with LTC2052IGN#PBF and AD8628ARUZ, the LTC2052HVIGN#PBF uniquely supports ±5V operation with 12V total supply, dual independent shutdown, and guaranteed performance across –40°C to 85°C - making it the only option for robust, multi-channel, bipolar-sensor front-ends in industrial data loggers.

FAQ
What is the maximum total supply voltage rating for the LTC2052HVIGN#PBF?
The LTC2052HVIGN#PBF is rated for a maximum total supply voltage of 12V, supporting ±5V operation (V+ = +5V, V– = –5V). This HV designation distinguishes it from standard LTC2052 variants rated for only 7V total supply. Exceeding 12V risks permanent damage per Absolute Maximum Ratings.
Does the LTC2052HVIGN#PBF support rail-to-rail input operation?
No, the LTC2052HVIGN#PBF does not support rail-to-rail input. Its input common-mode range extends from V– to V+ – 1.3V. For example, with ±5V supplies, inputs must stay within –5V to +3.7V. This limitation is inherent to its autozeroing architecture and must be accounted for in sensor interface design.
How does the shutdown function work on the LTC2052HVIGN#PBF?
The LTC2052HVIGN#PBF has two independent active-low shutdown pins: Pin 9 (SHDN A) controls amplifiers A and B; Pin 10 (SHDN B) controls amplifiers C and D. Pulling either pin below V– + 0.5V places its associated pair into shutdown, reducing per-amplifier supply current to ≤5μA while placing outputs in high-impedance state.
What is the typical input-referred clock feedthrough level of the LTC2052HVIGN#PBF?
The LTC2052HVIGN#PBF exhibits <1μVRMS input-referred clock feedthrough at its 7.5kHz autozeroing frequency. This residual artifact arises from internal sampling and is amplified by closed-loop gain. It can be suppressed using a feedback capacitor or by band-limiting the signal path below 7.5kHz.
Is the LTC2052HVIGN#PBF pin-compatible with other LTC2052 variants in the GN package?
Yes, all LTC2052 variants in the GN16 (16-lead SSOP) package - including LTC2052IGN#PBF, LTC2052HVIGN#PBF, and LTC2052HGN - share identical pinout, footprint, and solder pad layout. The HV suffix denotes enhanced voltage rating only; no PCB redesign is needed when upgrading from non-HV to HV versions in the same package.
