Product details
Overview
LTC2052HGN#TRPBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier in a 16-lead SSOP 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 single 2.7 V or dual ±5 V supplies and supports high-precision DC-coupled applications including thermocouple amplification and strain gauge signal conditioning in industrial sensor interfaces.
For engineers reviewing the LTC2052HGN#TRPBF datasheet, LTC2052HGN#TRPBF pinout, LTC2052HGN#TRPBF application, or LTC2052HGN#TRPBF equivalent, key selection criteria include guaranteed –40°C to 125°C operation, 3 MHz gain-bandwidth product, 1.5 μVP-P (0.01 Hz–10 Hz) input-referred noise, and verified CMRR/PSRR >125 dB over temperature.
Technical Context
The LTC2052HGN#TRPBF employs autozeroing architecture with a 7.5 kHz internal sampling clock to continuously correct input offset and drift. Its chopper-stabilized core achieves <1 μVRMS input-referred clock feedthrough at 7.5 kHz when source impedance remains below 10 kΩ.
It features extended common-mode input range (V– to V+ – 1.3 V), rail-to-rail output stage capable of driving 2 kΩ loads to both rails, and shutdown functionality (available on HV variants but not implemented in LTC2052HGN#TRPBF per package and marking data).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±3 μV maximum - enables sub-10 μV system-level DC error in precision sensor front-ends without calibration. |
| Offset Drift | ±30 nV/°C maximum - ensures <±0.3 μV total drift across –40°C to 125°C operating range. |
| Gain-Bandwidth Product | 3 MHz - supports stable closed-loop gain ≥10 up to ~300 kHz for anti-aliasing or active filtering. |
| Input Noise (0.01–10 Hz) | 1.5 μVP-P typical - critical for low-frequency DC measurements such as load cell or thermopile outputs. |
| CMRR / PSRR | ≥125 dB over full temperature range - rejects power supply ripple and common-mode interference in noisy industrial environments. |
| Supply Current per Amp | 1.0 mA typical at 3 V - balances ultra-precision performance with moderate power consumption in multi-channel systems. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, downhole, and industrial control applications. |

| 10 | –IN D | Inverting input of Amp D - part of matched quad topology; supports simultaneous multi-sensor buffering. |
| 11 | +IN D | Non-inverting input of Amp D - symmetrical layout minimizes thermal gradient-induced offset mismatch. |
| 12 | V– | Negative supply rail - connects to ground (single supply) or –5 V (dual supply); exposed pad tied here. |
| 13 | +IN C | Non-inverting input of Amp C - third channel input; enables 4-channel synchronous acquisition. |
| 14 | –IN C | Inverting input of Amp C - matched to Pin 13; supports independent gain-setting per channel. |

Key Features
| Feature | Design Value |
|---|---|
| Zero-drift autozeroing | Continuous offset correction eliminates thermal drift and time-dependent aging effects in long-duration DC measurements. |

| High CMRR/PSRR | ≥125 dB maintained across –40°C to 125°C - preserves accuracy in battery-powered or electrically noisy environments. |
| Low 0.01–10 Hz noise | 1.5 μVP-P typical - enables resolution of microvolt-level signals from high-impedance sensors without external filtering. |
| Quad-channel integration | Four matched amplifiers in one SSOP package - reduces PCB area and inter-channel mismatch vs discrete solutions. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar zero-drift op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052HVHGN#TRPBF | Supports ±5 V operation (vs. 2.7–5.5 V only for LTC2052HGN#TRPBF); otherwise identical specs and pinout. | Required for dual-supply designs needing true bipolar input/output swing beyond single-supply limits. | Select LTC2052HVHGN#TRPBF only if ±5 V rails are used; LTC2052HGN#TRPBF is optimal for 3.3 V or 5 V single-supply systems. |
| AD8629ARZ-REEL7 | Single 5 V supply only; 1 μV max offset, 0.02 μV/°C drift, but lower GBW (2.5 MHz) and higher noise (2.2 μVP-P). | Not quad-integrated; requires four separate packages for equivalent channel count, increasing board area and mismatch risk. | Choose AD8629ARZ-REEL7 only for single-channel, ultra-low-drift needs where space and cost allow discrete implementation. |
Compared with LTC2052HVHGN#TRPBF, the LTC2052HGN#TRPBF trades ±5 V dual-supply support for tighter qualification in single-rail industrial environments; versus AD8629ARZ-REEL7, it delivers integrated quad functionality with superior low-frequency noise and guaranteed high-temp operation - critical for compact, calibrated sensor modules.

FAQ
What is the maximum input offset voltage specification for the LTC2052HGN#TRPBF?
The LTC2052HGN#TRPBF has a maximum input offset voltage of ±3 μV over its full operating temperature range (–40°C to 125°C), as guaranteed by design and confirmed in production testing per the LTC2052H datasheet revision.
Does the LTC2052HGN#TRPBF support shutdown mode?
No, the LTC2052HGN#TRPBF does not include a shutdown pin. Shutdown functionality is only available on HV variants (e.g., LTC2052HVHGN#TRPBF) in MSOP or SO packages - the GN package variant lacks this feature entirely.

The LTC2052HGN#TRPBF operates from a single supply of 2.7 V to 5.5 V or dual supplies of ±2.7 V to ±5.5 V. It is not rated for ±5 V operation - that capability is exclusive to the HV suffix variants like LTC2052HVHGN#TRPBF.
Is the LTC2052HGN#TRPBF pin-compatible with other LTC2052 variants in the GN package?
Yes, all LTC2052 variants in the GN package (e.g., LTC2052CGN, LTC2052IGN, LTC2052HGN, LTC2052HVCGN, LTC2052HVIGN, LTC2052HVHGN) share identical pinout, footprint, and solder pad layout per LTC DWG #05-08-1641.
What is the guaranteed temperature range for the LTC2052HGN#TRPBF?
The LTC2052HGN#TRPBF is guaranteed to operate over the extended industrial temperature range of –40°C to 125°C, with all key DC parameters (offset, drift, CMRR, PSRR) specified and tested across this full range.
