Product details
Overview
LTC1151CSW#TRPBF from Analog Devices (formerly Linear Technology) is a dual, high-voltage, zero-drift operational amplifier in a 16-lead wide-body SOIC package. It delivers ±0.5µV typical input offset voltage, 0.01µV/°C max drift, 1.5µVP-P (0.1Hz–10Hz) input noise, 2.5MHz gain-bandwidth product, and operates from ±15V supplies - ideal for precision thermocouple and strain gauge amplification.
For engineers reviewing the LTC1151CSW#TRPBF datasheet, LTC1151CSW#TRPBF pinout, LTC1151CSW#TRPBF application, or LTC1151CSW#TRPBF equivalent, key selection criteria include ultra-low drift performance, integrated chopper architecture eliminating external sample-and-hold capacitors, high-voltage operation up to ±18V, and compatibility with standard dual op-amp sockets.
Technical Context
The LTC1151CSW#TRPBF implements a proprietary auto-zeroing chopper architecture with on-chip sampling capacitors per amplifier, eliminating external hold capacitors required by legacy chopper-stabilized op amps. Its high-voltage CMOS process enables full ±18V operation while maintaining rail-to-rail input common-mode range including ground.
Each amplifier features independent internal 1kHz sampling frequency, 140dB typical open-loop gain, and overload recovery of 3ms (positive) / 20ms (negative). The device supports single-supply operation from 4.75V to 36V and exhibits guaranteed 106dB minimum CMRR and 110dB minimum PSRR over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision zero-drift op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1151CN8 | Same die, 8-lead PDIP package; θJA = 130°C/W; no NC pins; wider lead pitch (0.300") | Better suited for prototyping, through-hole PCBs, and socket-based test fixtures | Select LTC1151CN8 when mechanical robustness, hand-soldering, or socket compatibility outweighs board space constraints. |
| LTC2051HS5#TRPBF | Single-channel, SOT-23-5; 0.25µV/°C max drift; 1.1µVP-P noise; 0.5mA supply current; max ±8V supply | Lower power, smaller footprint, but limited voltage range and single-channel only | Select LTC2051HS5#TRPBF for space-constrained, battery-powered, or single-amplifier nodes where ±8V rails suffice. |
Compared with LTC1151CN8, the LTC1151CSW#TRPBF offers superior thermal performance in reflow-soldered surface-mount assemblies and eliminates socket-related thermal EMF errors; versus LTC2051HS5#TRPBF, it provides dual-channel integration and ±18V operation at the cost of higher quiescent current and larger footprint.

The LTC1151CSW#TRPBF belongs to Linear's legacy high-precision zero-drift op amp family, designed specifically for DC-critical applications where microvolt-level offset stability, nanovolt-per-degree drift, and low 0.1Hz–10Hz noise dominate system accuracy requirements.
FAQ
What is the maximum total supply voltage rating for the LTC1151CSW#TRPBF?
The LTC1151CSW#TRPBF has an absolute maximum total supply voltage (V+ to V–) rating of 36V, enabling reliable operation at ±15V (30V total) and headroom up to ±18V. Exceeding 36V risks permanent damage. This rating is validated per Linear Technology's original Absolute Maximum Ratings table and applies to both continuous and transient conditions.
Does the LTC1151CSW#TRPBF require external capacitors for chopper stabilization?
No, the LTC1151CSW#TRPBF integrates all necessary sample-and-hold capacitors on-die - a key differentiator from earlier chopper op amps like the LTC1051. This eliminates two 100nF external capacitors per amplifier, reducing board area, component count, and potential leakage-induced errors. The architecture is confirmed in the "Description" section of the LTC1151 datasheet.
What is the guaranteed input offset voltage drift specification for the LTC1151CSW#TRPBF over temperature?
The LTC1151CSW#TRPBF guarantees a maximum average input offset voltage drift of ±0.05µV/°C over its full operating temperature range (0°C to 70°C), with a typical value of ±0.01µV/°C. This parameter is explicitly listed in the "Electrical Characteristics" table under "Average Input Offset Drift" with the ● symbol denoting full-temperature-range specification.
Can the LTC1151CSW#TRPBF operate from a single 5V supply?
Yes, the LTC1151CSW#TRPBF supports single-supply operation from 4.75V to 36V. At 5V, it maintains guaranteed PSRR down to ±2.35V rails and delivers usable output swing (e.g., 4.85V with 10kΩ load to ground). However, input common-mode range is reduced to 0V to 2.7V, and gain-bandwidth drops to 1.5MHz - details confirmed in the "Electrical Characteristics" tables for VS = 5V.
How does the LTC1151CSW#TRPBF handle overload recovery?
The LTC1151CSW#TRPBF recovers from positive saturation in 3ms typical and from negative saturation in 20ms typical, as specified in the "Typical Performance Characteristics" section. These values are measured under standard ±15V conditions with RL = 10kΩ and reflect the time for output to settle within 0.1% of final value after overdrive removal - critical for fast-cycling sensor systems.
