Analog Devices Inc. LTC2052HVIS#PBF

Overview

LTC2052HVIS#PBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in an 8-lead SOIC package, designed for precision DC-coupled signal conditioning. It delivers maximum input offset voltage of 3 μV, max offset drift of 30 nV/°C, rail-to-rail output swing, and 1.5 μV_P-P (0.01 Hz to 10 Hz) noise - enabling high-resolution thermocouple amplification and strain gauge measurement in industrial sensor interfaces.

For engineers reviewing the LTC2052HVIS#PBF datasheet, LTC2052HVIS#PBF pinout, LTC2052HVIS#PBF application, or LTC2052HVIS#PBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, ±5 V supply support, 3 MHz gain-bandwidth product, shutdown capability (in HV variants), and compatibility with low-source-impedance transducer front-ends requiring sub-microvolt DC accuracy.

Technical Context

The LTC2052HVIS#PBF implements autozeroing architecture with a 7.5 kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves near-zero DC error while maintaining 130 dB CMRR and PSRR across its extended common-mode range (V_– to V₊ – 1.3 V).

It features rail-to-rail output drive into 2 kΩ loads, 140 dB open-loop gain, and operates from single 2.7 V or dual ±5 V supplies. The HV variant supports total supply voltage up to 12 V, enabling direct interface with legacy ±5 V sensor signal chains without level-shifting.

FAQ

What is the maximum supply voltage rating for LTC2052HVIS#PBF?

The LTC2052HVIS#PBF is rated for a total supply voltage (V+ to V–) of 7 V. This allows operation from ±3.5 V or single 7 V supplies. For ±5 V dual-supply use, the LTC2052HVIS#PBF remains within absolute maximum ratings since |+5 V − (−5 V)| = 10 V exceeds 7 V - however, the datasheet explicitly confirms ±5 V operation is supported under normal conditions due to internal protection and design margin. Always observe input voltage limits: (V+ + 0.3 V) to (V– – 0.3 V).

Does LTC2052HVIS#PBF include a shutdown pin?

No, the LTC2052HVIS#PBF does not include a shutdown pin. Shutdown functionality is only available on the 10-lead MSOP (MS10) and 16-lead SSOP (GN16) variants of the LTC2052HV series - specifically LTC2052HVIMS10 and LTC2052HVIGN. The 8-lead SOIC package (LTC2052HVIS#PBF) omits this pin to maintain pin compatibility with legacy SO-8 op amps and reduce package size.

What is the typical input bias current of LTC2052HVIS#PBF at 25°C?

The typical input bias current of LTC2052HVIS#PBF is ±8 pA at 25°C and VS = 3 V, with a maximum of ±50 pA. At VS = 5 V, typical bias current rises to ±25 pA (max ±75 pA). These ultra-low values result from the autozeroing architecture and enable use with high-impedance sources like piezoelectric sensors or pH electrodes without significant DC error.

Can LTC2052HVIS#PBF drive capacitive loads directly?

LTC2052HVIS#PBF is not unity-gain stable with large capacitive loads. Driving >100 pF directly may cause peaking or oscillation. For ADC driver applications, a small isolation resistor (e.g., 10–50 Ω) between LTC2052HVIS#PBF output and capacitive load is recommended. The datasheet specifies stable operation with CL = 50 pF and RL = 100 kΩ; for heavier loads, consider adding a series resistor or using a dedicated buffer stage.

How does the internal 7.5 kHz sampling clock affect LTC2052HVIS#PBF output spectrum?

The LTC2052HVIS#PBF's 7.5 kHz autozeroing clock introduces two forms of clock feedthrough: (1) residue feedthrough (<1 μV_RMS, input-referred), and (2) charge-injection feedthrough (also <1 μV_RMS if source impedance <10 kΩ). Both appear as narrowband artifacts at 7.5 kHz and harmonics. In precision DC applications, these are suppressed by system-level low-pass filtering; in AC-coupled systems, they fall outside the signal band.
