Product details
Overview
LT6012ACS#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, <60µV max input offset voltage (A-grade), 135µA per amplifier supply current at 5V, and rail-to-rail output swing within 40mV of either supply rail. It is widely used in thermocouple amplifiers and battery-powered precision instrumentation.
For engineers reviewing the LT6012ACS#PBF datasheet, LT6012ACS#PBF pinout, LT6012ACS#PBF application, or LT6012ACS#PBF equivalent, this page provides verified package mapping (SO-14), confirmed quad-channel architecture, validated key specs including VOS drift (0.8µV/°C), CMRR (107–135dB), and real-world design context for low-voltage single-supply systems requiring long-term stability and sub-100µV accuracy.
Technical Context
The LT6012ACS#PBF implements a precision bipolar input stage with on-chip input bias current cancellation, enabling 300pA max IB while maintaining 120dB min open-loop gain at ±15V. Its rail-to-rail output stage uses complementary common-emitter followers to achieve 40mV saturation voltage at 1mA load under 5V single supply.
It operates across 2.7V to 36V total supply range (±1.35V to ±18V), with guaranteed performance over –40°C to 85°C (I-grade). Input common-mode range is limited to V– + 1V to V+ – 1.2V - distinct from output swing capability - and channel separation exceeds 110dB at DC, supporting tightly coupled multi-channel sensing without crosstalk-induced error.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 135µA per amplifier at 5V - enables ultra-low-power operation in always-on sensor front-ends. |
| Input Offset Voltage | ≤60µV (max, A-grade, 0°C to 70°C) - supports 16-bit+ system accuracy without trimming. |
| Input Noise Density | 14nV/√Hz at 1kHz - preserves SNR in precision photo-diode and bridge sensor interfaces. |
| Output Swing | Within 40mV of rails at no load (5V supply) - maximizes dynamic range in 3.3V or lower single-supply systems. |
| CMRR | 107–135dB - rejects common-mode interference in noisy industrial environments. |
| Gain Bandwidth | 250kHz (min) - sufficient for DC-coupled instrumentation, filter stages, and slow-settling ADC drivers. |
| Input Bias Current | ±300pA (max) - allows use with >10MΩ feedback networks without significant offset error. |
Pinout & Package
LT6012ACS#PBF is housed in a 14-lead plastic SO (Small Outline) package, 0.150-inch body width, with exposed pad not present. Pin 1 is marked by a beveled corner or dot; the device is lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Drives external load; rail-to-rail swing enables full utilization of 0–5V ADC reference. |
| 2 (–IN A) | Inverting input A | High-impedance node; requires guard ring layout to prevent leakage-induced offset. |
| 3 (+IN A) | Non-inverting input A | Accepts precision reference or sensor signal; input common-mode range limited to V– +1V to V+ –1.2V. |
| 4 (V+) | Positive supply | Accepts 2.7V–36V or ±1.35V–±18V; PSRR ≥112dB minimizes supply ripple coupling. |
| 5 (+IN B) | Non-inverting input B | Independent channel input; matched VOS and drift enable differential pair configurations. |
| 6 (–IN B) | Inverting input B | Paired with Pin 5 for matched dual-channel operation; ∆VOS ≤120µV (A-grade). |
| 7 (OUT B) | Amplifier B output | Electrically isolated output; channel separation ≥110dB prevents inter-channel crosstalk. |
| 8 (OUT D) | Amplifier D output | Fourth independent output; identical AC/DC specs to OUT A/B/C - supports 4-channel signal conditioning. |
| 9 (–IN D) | Inverting input D | Supports quad-channel simultaneous acquisition; input capacitance = 4pF limits high-Z source bandwidth. |
| 10 (+IN D) | Non-inverting input D | Enables four independent precision gain stages on one IC - reduces board area vs discrete op-amps. |
| 11 (V–) | Negative supply / ground reference | Return path for all four amplifiers; undersides not internally connected to V– in SO package. |
| 12 (+IN C) | Non-inverting input C | Third channel positive input; matches Pin 3 and Pin 5 for consistent multi-channel calibration. |
| 13 (–IN C) | Inverting input C | Third channel negative input; ∆IB ≤600pA (A-grade) ensures matched bias current error across channels. |
| 14 (OUT C) | Amplifier C output | Completes quad configuration; slew rate = 0.06V/µs supports stable closed-loop response up to ~20kHz. |

| 300pA max input bias current | Permits direct interface with high-impedance sources (e.g., pH electrodes, piezoelectric sensors) without guard buffers. |
| 120dB min open-loop gain (VS = ±15V) | Ensures <0.001% gain error in unity-gain buffer or 100× gain stages using standard 1% resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6012IS#PBF | I-grade (-40°C to 85°C) with same SO-14 package; VOS max = 75µV (vs 60µV for ACS); IB unchanged. | Required for extended temperature deployments where A-grade spec margin is unnecessary. | Select LT6012IS#PBF when full industrial temp range is needed but tighter offset spec is not cost-justified. |
| OPA2189IDR | Single-supply precision op-amp (TI); 5.6nV/√Hz noise, 25µV max VOS, 200µA supply current - lower noise but higher power. | Better for ultra-low-noise, moderate-power applications where 14nV/√Hz is insufficient. | Choose OPA2189IDR only if system SNR demands sub-10nV/√Hz and 135µA supply current is not constraining. |
Compared with LT6012IS#PBF, the LT6012ACS#PBF offers tighter offset voltage (60µV vs 75µV) for higher DC accuracy at room temperature, while the OPA2189IDR trades 40% higher supply current for nearly 3× lower input noise - making LT6012ACS#PBF optimal for battery-constrained, µV-level DC precision tasks.

FAQ
What is the maximum input common-mode voltage range for LT6012ACS#PBF?
The LT6012ACS#PBF has an input common-mode voltage range of V– + 1V to V+ – 1.2V - it does not support rail-to-rail inputs. For example, with a 5V/0V supply, valid input range is 1V to 3.8V. Exceeding this range causes gain collapse but no phase reversal. This limitation is explicitly defined in the datasheet Absolute Maximum Ratings and Applications Information sections.
Does LT6012ACS#PBF support true rail-to-rail output operation?
Yes, the LT6012ACS#PBF delivers rail-to-rail output swing: within 40mV of either supply rail at no load (5V supply), and within 120–220mV at 1mA source/sink current. This is confirmed in the Electrical Characteristics table under "Maximum Output Swing" and validated in Typical Performance Characteristic Figure G30 (rail-to-rail output swing plot).
What is the guaranteed operating temperature range for LT6012ACS#PBF?
The LT6012ACS#PBF is specified for 0°C to 70°C (C-grade with A-level offset spec). The "A" in ACS denotes the A-grade offset voltage performance (≤60µV max), while "C" indicates commercial temperature range. Full –40°C to 85°C operation is guaranteed only for LT6012IS#PBF and LT6012AIS#PBF variants.
How many amplifiers does LT6012ACS#PBF contain, and are they matched?
The LT6012ACS#PBF contains four independent precision op-amps in a single SO-14 package. Matching specifications are guaranteed: offset voltage match (∆VOS) ≤120µV, input bias current match (∆IB) ≤600pA, and CMRR match (∆CMRR) ≥101dB - all tested over the full 0°C to 70°C range per the Electrical Characteristics tables.
Can LT6012ACS#PBF drive capacitive loads, and what is the limit?
Yes, the LT6012ACS#PBF can drive up to 500pF capacitive loads in unity-gain configuration, as stated in the Applications Information section. 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.
