Analog Devices Inc. LTC2052HVHS#PBF

Overview

LTC2052HVHS#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in an 8-lead SOIC package, delivering ultra-low input offset voltage (±3 μV max), near-zero drift (30 nV/°C max), and rail-to-rail output swing. It operates from ±5 V supplies (12 V total) and supports high-precision DC-coupled applications including thermocouple amplification, strain gauge signal conditioning, and medical instrumentation.

For engineers reviewing the LTC2052HVHS#PBF datasheet, LTC2052HVHS#PBF pinout, LTC2052HVHS#PBF application, or LTC2052HVHS#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, 3 MHz gain-bandwidth product, 1.5 μV_P-P (0.01 Hz–10 Hz) input-referred noise, and HV-rated supply tolerance - critical for industrial sensor front-ends requiring long-term DC stability.

Technical Context

The LTC2052HVHS#PBF employs autozeroing architecture with a 7.5 kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves <1 μV_RMS clock feedthrough (input-referred) at 7.5 kHz when source impedance is <10 kΩ.

It features extended common-mode input range (V_– to V₊ – 1.3 V), 140 dB typical open-loop gain, and enhanced output stage capable of driving 2 kΩ loads to both rails - enabling direct interfacing with SAR ADCs and low-impedance sensors without external buffers.

FAQ

What is the maximum total supply voltage for LTC2052HVHS#PBF?

The LTC2052HVHS#PBF supports a maximum total supply voltage of 12 V, enabling operation from ±5 V rails. This HV rating distinguishes it from standard LTC2052 variants (7 V max), allowing direct use with legacy industrial bipolar supplies without regulation. Absolute maximum ratings specify V+ to V– ≤ 12 V; exceeding this risks permanent damage.

Does LTC2052HVHS#PBF include shutdown functionality?

No, LTC2052HVHS#PBF does not feature a shutdown pin. Shutdown capability is only available in MSOP packages (e.g., LTC2052HVIMS10) with dedicated SHDN pins. The SOIC-packaged LTC2052HVHS#PBF draws 0.85 mA per amplifier at ±5 V and remains fully active at all times - appropriate for always-on measurement systems where power cycling is unnecessary.

How does the autozeroing architecture of LTC2052HVHS#PBF affect its noise performance?

LTC2052HVHS#PBF uses a 7.5 kHz autozeroing clock to correct offset and drift, resulting in 1.5 μV_P-P (0.01–10 Hz) input-referred noise - ideal for DC and low-frequency measurements. Clock feedthrough is minimized to <1 μV_RMS input-referred when source impedance stays below 10 kΩ, preserving signal integrity in precision sensor interfaces.

Can LTC2052HVHS#PBF drive capacitive loads directly?

LTC2052HVHS#PBF is stable with capacitive loads up to 100 pF when configured as a unity-gain follower (AV = 1). For larger loads (e.g., ADC input capacitance >100 pF), a series resistor (10–50 Ω) between output and load is required to maintain phase margin >45°. The datasheet confirms stability under CL = 100 pF, RL = 100 kΩ conditions.

What is the guaranteed operating temperature range for LTC2052HVHS#PBF?

LTC2052HVHS#PBF is guaranteed to operate from –40°C to 125°C, matching the H-grade specification. This extended range is validated across all electrical parameters in the datasheet's "LTC2052H/LTC2052HVH" column, including offset voltage, drift, CMRR, and supply current - making it suitable for under-hood automotive, downhole, and industrial control applications.
