Analog Devices Inc. LTC2052HGN#PBF

Overview

LTC2052HGN#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, 1.5μV_P-P (0.01Hz–10Hz) input-referred noise, rail-to-rail output swing, and operates from 2.7V single supply or ±5V dual supply. It is used in thermocouple amplifiers, strain gauge interfaces, and high-resolution data acquisition systems.

For engineers reviewing the LTC2052HGN#PBF datasheet, LTC2052HGN#PBF pinout, LTC2052HGN#PBF application, or LTC2052HGN#PBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, zero-drift architecture for long-term DC stability, low 0.75mA per amplifier supply current, and compatibility with high-impedance sensor sources requiring sub-microvolt offset performance.

Technical Context

The LTC2052HGN#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 errors while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate.

It features extended common-mode input range (V_– to V₊ – 1.3V), rail-to-rail output stage capable of driving 2kΩ loads to both rails, and robust PSRR (130dB) and CMRR (130dB) across temperature - enabling stable operation in noisy industrial environments with wide supply and common-mode variations.

FAQ

What is the maximum operating temperature specification for the LTC2052HGN#PBF?

The LTC2052HGN#PBF is specified for continuous operation from –40°C to +125°C. This extended temperature range is guaranteed per datasheet Section "Available Options", where "H" grade denotes the highest temperature rating. The device maintains full performance including offset voltage, drift, and noise specifications across this entire range, making it suitable for under-hood automotive and industrial control applications.

Does the LTC2052HGN#PBF include shutdown functionality?

No, the LTC2052HGN#PBF does not include a shutdown pin. Shutdown capability is only present in the MSOP variants (e.g., LTC2052CMS10) with 10-lead packages. The GN package (16-lead SSOP) used by LTC2052HGN#PBF has no dedicated SHDN pin - all four amplifiers operate continuously when powered. Power reduction must be achieved externally via supply gating.

What is the input bias current specification for the LTC2052HGN#PBF at 125°C?

At 125°C, the input bias current for the LTC2052HGN#PBF is ±150pA maximum per input, as confirmed in the "LTC2051H/LTC2052H" column of the Electrical Characteristics table (Page 4, Note 4). This value accounts for elevated ESD diode leakage and remains well below 1nA, preserving accuracy in high-impedance sensor interfaces such as pH electrodes or piezoresistive sensors.

Can the LTC2052HGN#PBF drive a 10kΩ load to rail-to-rail output swing?

Yes, the LTC2052HGN#PBF guarantees rail-to-rail output swing into 10kΩ loads. Per the Electrical Characteristics table (Page 4), the output voltage swing high is V+ – 0.02V and swing low is 2mV above V– under RL = 10kΩ to GND conditions at 25°C - and these values are maintained across the full –40°C to +125°C range. This enables direct interfacing with 5V ADCs without external level-shifting circuitry.

Is the LTC2052HGN#PBF RoHS-compliant and lead-free?

Yes, the "#PBF" suffix in LTC2052HGN#PBF explicitly denotes lead-free (Pb-free) and RoHS-compliant packaging per Analog Devices' standard marking convention. The device meets EU RoHS Directive 2011/65/EU and is compatible with standard SnAgCu reflow profiles. Full compliance documentation, including substance declarations and test reports, is available through Analog Devices' Quality & Reliability portal.
