Analog Devices Inc. LTC2052HVIS

Overview

LTC2052HVIS 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 - ideal for precision thermocouple amplification, strain gauge signal conditioning, and high-resolution data acquisition systems operating from ±5V supplies.

For engineers reviewing the LTC2052HVIS datasheet, LTC2052HVIS pinout, LTC2052HVIS application, or LTC2052HVIS equivalent, key selection criteria include guaranteed –40°C to 85°C operation, ±5V supply compatibility, 3 MHz gain-bandwidth product, 1.5 μV_P-P (0.01–10 Hz) input-referred noise, and verified CMRR/PSRR >120 dB across temperature.

Technical Context

The LTC2052HVIS employs autozeroing architecture with a 7.5 kHz internal sampling clock to continuously correct input offset and drift. Its dual-stage chopper-stabilized design achieves DC accuracy without compromising bandwidth or introducing significant clock feedthrough when source impedances remain below 10 kΩ.

It features enhanced input common-mode range (V_– to V₊ – 1.3 V), rail-to-rail output drive into 2 kΩ loads, and shutdown capability (not implemented in SO-8 variant per package constraints). All four amplifiers share identical electrical specifications and operate independently within a single monolithic die.

Supply support for LTC2052HVIS includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

Analog Devices acquired Linear Technology in 2017 and maintains full technical and manufacturing continuity for the LTC portfolio. Linear's precision analog heritage underpins industry-leading zero-drift op amp performance.

The LTC2052 belongs to Linear's zero-drift operational amplifier family, designed specifically for DC-accurate signal conditioning in instrumentation, medical, and industrial sensing applications where offset, drift, and low-frequency noise dominate system error budgets.

FAQ

What is the maximum supply voltage for the LTC2052HVIS?

The LTC2052HVIS supports a total supply voltage of up to 12 V, enabling operation from ±5V (10 V) or single 12 V rails. Absolute maximum ratings specify V+ to V– ≤ 12 V; exceeding this risks permanent damage. For ±5V use, connect Pin 4 (V–) to –5 V and Pin 8 (V+) to +5 V. The LTC2052HVIS is explicitly characterized and guaranteed for ±5V operation across its full –40°C to 85°C range.

Does the LTC2052HVIS include a shutdown pin?

No, the LTC2052HVIS in the 8-lead SOIC (S8) package does not incorporate a shutdown pin. Shutdown functionality is only available in MSOP variants (e.g., LTC2052HVIMS10) with dedicated SHDN pins. The LTC2052HVIS draws 0.85 mA per amplifier at ±5V and cannot be externally disabled; power cycling is required to reduce quiescent current.

How does the LTC2052HVIS achieve its ultra-low offset voltage?

The LTC2052HVIS uses continuous autozeroing with a 7.5 kHz internal clock to sample and cancel input offset voltage in real time. This chopper-stabilized architecture corrects both initial offset and temperature-induced drift, achieving ±3 μV max offset and ±30 nV/°C max drift - verified across –40°C to 85°C. Unlike traditional choppers, it minimizes switching artifacts through correlated double sampling.

Can the LTC2052HVIS drive capacitive loads directly?

The LTC2052HVIS is not unity-gain stable into pure capacitive loads >100 pF. Driving ADC inputs or cables requires isolation via a series resistor (≥100 Ω) or use of the amplifier in non-inverting configuration with ≥10 gain. Layout best practices include minimizing trace capacitance at the output and placing feedback components close to the device to maintain phase margin.

Is the LTC2052HVIS pin-compatible with other LTC2052 variants?

The LTC2052HVIS shares identical pinout with all 14-lead SOIC variants (e.g., LTC2052HVCS, LTC2052IS), but is not pin-compatible with 16-lead SSOP (GN16) or MSOP packages. Pin 1 (OUT A) through Pin 8 (V+) follow JEDEC MS-012 SOIC standard; however, GN16 adds NC pins and splits supply connections, while MSOP variants relocate V–/V+ and add SHDN pins - requiring PCB redesign for substitution.
