Product details
Overview
LT6012AIGN#PBF from Analog Devices (formerly Linear Technology) is a quad precision rail-to-rail output operational amplifier optimized for low-noise, low-power, high-accuracy signal conditioning. It delivers 14nV/√Hz input voltage noise, ≤85µV max input offset voltage (–40°C to 85°C), 300pA max input bias current, and 135µA supply current per amplifier on 5V. It is used in thermocouple amplifiers, precision photodiode front-ends, and battery-powered instrumentation.
For engineers reviewing the LT6012AIGN#PBF datasheet, LT6012AIGN#PBF pinout, LT6012AIGN#PBF application, or LT6012AIGN#PBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, matched quad-channel performance (≤170µV offset match), SSOP-16 package compatibility, and rail-to-rail output swing within 40mV of rails at 1mA load.
Technical Context
The LT6012AIGN#PBF employs a precision bipolar input stage with on-chip trimming to achieve sub-100µV offset and 0.8µV/°C drift. Its internal back-to-back diode input protection and 500Ω series resistors enable robust 10V differential input tolerance without external components.
It operates from 2.7V single supply to ±18V dual supply, maintaining 120dB minimum open-loop gain and 112dB PSRR across its full voltage range. Channel separation exceeds 110dB, supporting tightly coupled multi-channel sensing where crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤85 µV over –40°C to 85°C - ensures <1 LSB error in 16-bit systems with 5V full-scale. |
| Input Bias Current | ±300 pA max - enables use with >10MΩ feedback/source impedances without significant DC error. |
| Supply Current per Amp | 135 µA at 5V - supports ultra-low-power operation in always-on sensor nodes and portable devices. |
| Input Noise Density | 14 nV/√Hz at 1kHz - preserves SNR in low-level analog front-ends such as strain gauge or RTD bridges. |
| Rail-to-Rail Output Swing | Within 40 mV of V+ and V– at 1mA load - maximizes dynamic range in single-supply 3.3V or 5V systems. |
| Gain Bandwidth Product | 250 kHz - sufficient for DC-coupled instrumentation, filter stages, and slow-slewing control loops. |
| Common Mode Rejection | 107 dB min - rejects power supply ripple and ground bounce in noisy industrial environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6012IGN#PBF | Same quad architecture and SSOP-16 package, but I-grade (–40°C to 85°C) with looser offset spec (≤125µV). | Suitable for cost-sensitive industrial designs where full A-grade matching isn't required. | Select LT6012AIGN#PBF when guaranteed ≤85µV offset and ≤170µV channel match are mandatory for metrology-grade accuracy. |
| AD8628ARUZ | Single-channel, 5V-only, 1µV max offset, but higher 1.5mA supply current and no quad option. | Used in ultra-high-precision single-channel applications like reference buffers or DAC output stages. | Choose LT6012AIGN#PBF for multi-channel, low-power, wide-supply flexibility; AD8628ARUZ only where sub-µV offset justifies higher power and board area. |
Compared with LT6012IGN#PBF, the LT6012AIGN#PBF provides tighter offset and matching specs essential for calibrated instrumentation; versus AD8628ARUZ, it trades absolute offset precision for quad integration, lower power, and broader supply range - making it optimal for compact, battery-aware multi-sensor systems.

FAQ
What is the maximum input common-mode voltage range for LT6012AIGN#PBF?
The LT6012AIGN#PBF input stage operates from V– + 1V to V+ – 1.2V. For example, with a 5V/0V supply, the valid input range is 1V to 3.8V. Exceeding this range causes gain collapse but no phase reversal. This specification is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of the official LT6011/LT6012 datasheet.
Does LT6012AIGN#PBF support single-supply operation?
Yes, LT6012AIGN#PBF operates from a single 2.7V to 36V supply. Its rail-to-rail output swings within 40mV of both rails at 1mA load, and input common-mode range extends to within 1V of each rail. This makes LT6012AIGN#PBF well-suited for 3.3V and 5V single-supply systems common in portable and industrial sensors.
What is the guaranteed offset voltage specification for LT6012AIGN#PBF over temperature?
LT6012AIGN#PBF guarantees ≤85 µV maximum input offset voltage over the full –40°C to 85°C operating temperature range. This A-grade specification is explicitly listed in the Electrical Characteristics table for LT6012AGN devices under "TA = –40°C to 85°C" conditions, confirming its suitability for uncalibrated industrial applications.
Can LT6012AIGN#PBF drive capacitive loads?
Yes, LT6012AIGN#PBF can drive up to 500pF in unity-gain configuration. Stability improves with higher closed-loop gain, and adding a small series resistor (e.g., 10–50Ω) between output and load further enhances capacitive drive capability. This behavior is verified in the "Capacitive Loads" section of the Applications Information.
How does LT6012AIGN#PBF differ from LT6012CS#PBF?
LT6012AIGN#PBF is an A-grade, –40°C to 85°C qualified part in 16-pin SSOP (GN) packaging, with tighter offset (≤85µV) and matching specs. LT6012CS#PBF is a commercial-grade (0°C to 70°C), SO-14 packaged version with looser offset (≤100µV) and no extended temperature guarantee. The GN package also offers better thermal performance than SO-14 for sustained operation.
