Product details
Overview
LT6011AIS8#PBF from Analog Devices (formerly Linear Technology) is a dual precision rail-to-rail output operational amplifier optimized for low-power, high-accuracy signal conditioning. It delivers 135µA supply current per amplifier, 14nV/√Hz input voltage noise, and ≤60µV maximum input offset voltage over –40°C to 85°C - enabling use in thermocouple amplifiers, battery-powered instrumentation, and precision photo diode front-ends.
For engineers reviewing the LT6011AIS8#PBF datasheet, LT6011AIS8#PBF pinout, LT6011AIS8#PBF application, or LT6011AIS8#PBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, 2.7V to 36V single-supply compatibility, 40mV output swing to rails at 1mA load, and matched dual-channel performance with ≤120µV offset match.
Technical Context
The LT6011AIS8#PBF employs a precision bipolar input stage with on-chip trimming to achieve sub-60µV offset and 0.8µV/°C max drift. Its rail-to-rail output stage uses complementary NPN/PNP drivers to deliver 1mA sink/source capability while maintaining linearity within 40mV of either supply rail.
Input bias current is trimmed to ±300pA max across temperature, enabled by an internal cancellation circuit that decouples IB+ and IB– - requiring asymmetric PCB layout guard strategies rather than matched input resistances for optimal DC accuracy.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 36V - supports single-supply industrial sensors and dual ±15V legacy systems without level-shifting. |
| Input Offset Voltage | ≤60µV (–40°C to 85°C) - enables <0.01% error in 10V full-scale 16-bit DAC buffers without calibration. |
| Supply Current | 135µA per amplifier - allows dual-channel precision gain/offset correction in coin-cell-powered IoT nodes. |
| Output Swing | Within 40mV of V+ and V– at 1mA load - preserves dynamic range in 3.3V ADC driver stages. |
| Input Noise Density | 14nV/√Hz @ 1kHz - maintains SNR >90dB for 10kΩ source impedances in medical ECG front-ends. |
| CMRR | 107dB min (–40°C to 85°C) - rejects common-mode interference in bridge sensor interfaces with <1µV error. |
| Gain Bandwidth | 225kHz min - sufficient for DC–10kHz sensor signal conditioning with ≥40dB closed-loop gain stability. |
Pinout & Package
LT6011AIS8#PBF is housed in an 8-lead plastic SO (S8) package with standard narrow-body 150-mil width and 1.27mm pitch. The exposed pad is absent; thermal resistance θJA = 190°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives external load; rail-to-rail swing enables full utilization of 3.3V ADC reference. |
| 2 (–IN A) | Inverting input A | High-impedance node; requires guard ring routing to suppress leakage-induced offset errors. |
| 3 (+IN A) | Non-inverting input A | Accepts DC-coupled sensor signals up to V+ – 1.2V; not rail-to-rail input capable. |
| 4 (V–) | Negative supply | Reference for both amplifiers; undersides of DFN variants connect here, but S8 has isolated lead. |
| 5 (V+) | Positive supply | Supports single 2.7–36V or dual ±1.35–±18V operation; PSRR ≥112dB rejects supply ripple. |
| 6 (OUT B) | Amplifier B output | Independent output; channel separation ≥110dB prevents crosstalk in dual-sensor systems. |
| 7 (–IN B) | Inverting input B | Matched to Pin 2; offset match ≤120µV ensures consistent gain in differential configurations. |
| 8 (+IN B) | Non-inverting input B | Electrically identical to Pin 3; enables simultaneous dual-channel signal processing on one die. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 40mV of V+ and V– at 1mA load - maximizes usable voltage range in low-voltage systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP2177ARZ-REEL7 | Higher 600µV max offset, 1.3µV/°C drift, but 1.8MHz GBW and lower 3.7nV/√Hz noise. | Better for higher-bandwidth precision filters; less suitable for ultra-low-offset DC-coupled sensors. | Select when bandwidth >100kHz required and offset <100µV is acceptable. |
| AD8628ARZ-REEL7 | Zero-drift architecture, 1µV max offset, but 2.5mA supply current and limited 5.5V max supply. | Ideal for zero-error DC measurement; unsuitable for 12V/24V industrial supplies or battery longevity. | Select when sub-5µV offset is mandatory and power budget allows >18× higher current draw. |
Compared with OP2177ARZ-REEL7 and AD8628ARZ-REEL7, LT6011AIS8#PBF uniquely balances ultra-low offset (≤60µV), rail-to-rail output, and micropower operation (135µA) across 2.7–36V supplies - making it optimal for wide-input-range, battery-constrained precision analog front-ends.

FAQ
What is the maximum input common mode voltage range for LT6011AIS8#PBF?
The LT6011AIS8#PBF input stage operates from V– + 1V to V+ – 1.2V. For example, with a 5V/0V supply, inputs must stay within 1V to 3.8V. Exceeding this range causes gain collapse but no phase reversal - critical for protecting sensor interfaces during power sequencing.
Does LT6011AIS8#PBF support true rail-to-rail input operation?
No, LT6011AIS8#PBF does not support rail-to-rail input. Its input common mode range is limited to V– + 1V to V+ – 1.2V. However, its rail-to-rail output swing (within 40mV of rails) is fully functional - making it ideal for configurations like inverting amplifiers where inputs remain near virtual ground.
What is the guaranteed input offset voltage specification for LT6011AIS8#PBF over temperature?
LT6011AIS8#PBF guarantees ≤60µV maximum input offset voltage across the full –40°C to 85°C operating temperature range. This is specified for the "A" grade in SO-8 packaging and confirmed in the Electrical Characteristics table under VS = 5V, 0V conditions.
Can LT6011AIS8#PBF drive capacitive loads, and what is the limit?
Yes, LT6011AIS8#PBF can drive up to 500pF capacitive loads in unity-gain configuration. Stability improves with higher closed-loop gain. Adding a small series resistor (e.g., 10–50Ω) between output and load further enhances phase margin for larger capacitances encountered in ADC input buffering.
How does the input bias current matching of LT6011AIS8#PBF affect differential applications?
LT6011AIS8#PBF specifies ≤120µV offset match and ≤600pA input bias current match between its two amplifiers. This tight matching ensures minimal common-mode error in dual-amplifier circuits like instrumentation amplifiers - preserving CMRR even when using high-value, temperature-sensitive feedback resistors.
