Product details
Overview
LTC2052IS#TRPBF from Analog Devices (formerly Linear Technology) is a quad zero-drift operational amplifier optimized for precision DC-coupled signal conditioning in high-resolution data acquisition systems. It delivers maximum input offset voltage of 3μV, maximum offset drift of 30nV/°C, rail-to-rail output swing, and 1.5μVP-P (0.01Hz–10Hz) input-referred noise - enabling accurate amplification of microvolt-level sensor signals such as thermocouples and strain gauges.
For engineers reviewing the LTC2052IS#TRPBF datasheet, LTC2052IS#TRPBF pinout, LTC2052IS#TRPBF application, or LTC2052IS#TRPBF equivalent, key selection criteria include guaranteed –40°C to +85°C operation, SO-14 package compatibility, dual-supply (±5V) and single-supply (2.7V–5.5V) support, and verified performance in low-side current sensing and medical instrumentation circuits.
Technical Context
The LTC2052IS#TRPBF 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 error while maintaining 3MHz gain-bandwidth product and 2V/μs slew rate - balancing precision and dynamic response for DC-accurate active filters and closed-loop sensor interfaces.
It features extended common-mode input range (V– to V+ – 1.3V), 130dB typical PSRR and CMRR, and rail-to-rail output stage capable of driving 2kΩ loads to both supply rails - supporting robust operation in noisy industrial environments and battery-powered portable instrumentation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC2052IGN#TRPBF | Same quad zero-drift core but in 16-lead SSOP (GN16) package; identical electrical specs and temp range. | Preferred for higher-density PCB layouts where 14-lead SO footprint is unavailable or thermal performance requires larger pad area. | Select when board space constraints favor SSOP or when θJA = 110°C/W (vs. 110°C/W for SO-14) improves thermal margin in sealed enclosures. |
| LTC2052HVIS#TRPBF | Extended temperature grade (–40°C to +125°C); otherwise identical SO-14 package and electrical performance. | Suitable for under-hood automotive or high-temp industrial control where ambient exceeds +85°C. | Choose only if system-level thermal validation confirms sustained operation above +85°C; adds cost with no benefit below that threshold. |
Compared with LTC2052IS#TRPBF, the IGN variant offers identical precision in a smaller-footprint SSOP for space-constrained designs, while the HVIS variant extends operating range to +125°C for harsh-environment applications - neither provides pin-compatible replacement without layout revision.

FAQ
What is the maximum input offset voltage specification for LTC2052IS#TRPBF?
The maximum input offset voltage for LTC2052IS#TRPBF is ±3μV across the full –40°C to +85°C operating temperature range, as guaranteed by design and validated during production testing. This value applies to all four amplifiers in the LTC2052IS#TRPBF package and enables direct amplification of microvolt-level sensor outputs without trimming or calibration in applications like thermocouple measurement and precision weighing.
Does LTC2052IS#TRPBF support single-supply operation?
Yes, LTC2052IS#TRPBF supports true single-supply operation from 2.7V to 5.5V. Its input common-mode range extends from the negative supply (V–) to V+ – 1.3V, and its rail-to-rail output swings within 15mV of both rails into 2kΩ loads - making it suitable for 3.3V and 5V microcontroller-based systems without level-shifting circuitry. The LTC2052IS#TRPBF also operates with dual supplies up to ±5V.
What is the noise performance of LTC2052IS#TRPBF in the 0.01Hz to 10Hz band?
LTC2052IS#TRPBF delivers 1.5μVP-P input-referred noise in the 0.01Hz to 10Hz band, measured with RS = 100Ω. This ultra-low flicker noise enables high-resolution DC measurements in applications such as electronic scales and medical instrumentation, where signal bandwidth is narrow and baseline stability is critical. The LTC2052IS#TRPBF achieves this performance through continuous autozeroing without sacrificing gain-bandwidth or slew rate.
Is LTC2052IS#TRPBF pin-compatible with other packages in the LTC2052 family?
No, LTC2052IS#TRPBF is not pin-compatible with other LTC2052 variants. It uses the 14-lead SO (S14) package with specific pin assignments including NC on Pin 8. The LTC2052IGN#TRPBF uses a 16-lead SSOP (GN16) package with different pin count and layout, and the LTC2052HVIS#TRPBF shares the same SO-14 footprint but is not a drop-in replacement due to extended temperature qualification and potential minor process differences. Board redesign is required when switching between these packages.
What is the shutdown functionality of LTC2052IS#TRPBF?
LTC2052IS#TRPBF does not include a shutdown pin; shutdown capability is only present in the 10-lead MSOP variants of the LTC2051 (e.g., LTC2051CMS10). The LTC2052IS#TRPBF is a fixed-function quad op amp with no enable/disable control. Power management must be implemented externally via supply rail switching or series FETs if low-quiescent operation is required between measurement cycles.
