Product details
Overview
LT6010AIDD#PBF from Analog Devices (formerly Linear Technology) is a precision rail-to-rail output operational amplifier optimized for low-noise, low-input-bias-current, and ultra-low-offset applications including thermocouple amplification, photodiode signal conditioning, and instrumentation front-ends. It delivers 35µV max input offset voltage, 110pA max input bias current, 135µA supply current, 14nV/√Hz input voltage noise, and operates from 2.7V to ±18V supplies.
For engineers reviewing the LT6010AIDD#PBF datasheet, LT6010AIDD#PBF pinout, LT6010AIDD#PBF application, or LT6010AIDD#PBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation, DFN-8 package thermal performance (θJA = 160°C/W), shutdown mode (12µA IQ), and verified rail-to-rail output swing within 40mV of rails at 1mA load.
Technical Context
The LT6010AIDD#PBF uses an internally trimmed bipolar input stage with on-chip cancellation circuitry to achieve sub-35µV offset and 0.8µV/°C max drift. Its input protection includes 500Ω series resistors and back-to-back diodes, enabling safe operation with differential inputs up to 10V.
It features a dedicated SHDN pin that disables the amplifier core when pulled ≥2V above V–, reducing quiescent current to 12µA while maintaining input connectivity - precluding use in multiplexing but enabling power-gating in battery-powered systems. The output drives capacitive loads up to 500pF in unity gain without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 35µV at 0°C to 70°C; ensures ≤0.35mV error in 10V full-scale precision measurement systems |
| Input Bias Current | Max ±110pA at 0°C to 70°C; enables accurate amplification of high-impedance sources (e.g., photodiodes, RTDs) |
| Supply Current | 135µA typical at 5V; supports >10-year battery life in 10µA-average-power sensor nodes |
| Output Swing | Rail-to-rail: within 40mV of V+ or V– at 1mA load; preserves dynamic range in 3.3V single-supply systems |
| Input Noise Density | 14nV/√Hz at 1kHz; dominates system noise only for source impedances <20kΩ |
| Gain Bandwidth | 250kHz min; sufficient for DC–10kHz sensor signal chains with ≥20dB closed-loop gain |
| CMRR | 107dB min over full temperature range; rejects common-mode interference in noisy industrial environments |
| Shutdown Current | 12µA max; reduces standby power by >90% vs active mode in intermittent-sampling architectures |
Pinout & Package
LT6010AIDD#PBF is housed in an 8-lead 3mm × 3mm plastic DFN package with exposed thermal pad internally connected to V–. PCB connection to the exposed pad is optional but recommended for optimal thermal performance (θJA = 160°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NULL | No internal connection; must be left unconnected or tied to ground per layout best practices |
| 2 | –IN | Inverting input; low-bias-current node requiring guarded routing in high-Z applications |
| 3 | +IN | Non-inverting input; matched to –IN for CMRR optimization; avoid asymmetry in trace length |
| 4 | V– | Negative supply rail and thermal pad reference; connect exposed pad to V– plane for thermal relief |
| 6 | V+ | Positive supply rail; decouple with ≥0.1µF ceramic capacitor close to pin |
| 7 | OUT | Amplifier output; capable of sourcing/sinking 10mA; drive capacitive loads ≤500pF directly |
| 8 | SHDN | Active-low shutdown control; logic threshold is V– + 0.2V (on) / V– + 2.0V (off); internal 85kΩ pull-down |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed Input Offset | 35µV max over 0°C–70°C enables direct replacement of legacy op amps in 16-bit ADC front-ends without recalibration |

| Low Input Bias Current | ±110pA max allows use with >10MΩ feedback networks and high-impedance sensors without significant DC error |
| Integrated Shutdown | Reduces supply current to 12µA while preserving input connectivity - ideal for duty-cycled sensor acquisition |
| Robust Input Protection | 500Ω series resistors + back-to-back diodes limit input current to 10mA at 10V differential, eliminating need for external clamps |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Zero-drift auto-zero architecture; 10µV max VOS, 0.02µV/°C drift, but higher 17µA IQ and no shutdown pin | Better DC accuracy for <100Hz applications; unsuitable where shutdown sequencing or low-frequency noise (<0.1Hz) matters | Choose OPA333AIDBVR when long-term drift stability outweighs power budget and shutdown capability |
| LTC2050CMS8#PBF | Chopper-stabilized; 1µV max VOS, 0.015µV/°C drift, 1.5MHz GBW, but 1.1mA IQ and no rail-to-rail output | Superior low-frequency precision for DC-coupled medical sensors; incompatible with rail-limited 3.3V systems due to 150mV output headroom | Choose LTC2050CMS8#PBF for ultra-high-precision DC measurements where power and output swing are secondary |
Compared with OPA333AIDBVR and LTC2050CMS8#PBF, LT6010AIDD#PBF uniquely balances sub-35µV offset, 135µA supply current, integrated shutdown, and rail-to-rail output - making it optimal for portable, battery-constrained precision analog front-ends requiring moderate bandwidth and thermal stability.

FAQ
What is the maximum operating temperature range for LT6010AIDD#PBF?
The LT6010AIDD#PBF is fully specified and guaranteed over the industrial temperature range of –40°C to +85°C. Its DFN package has a maximum junction temperature of 125°C and thermal resistance θJA = 160°C/W, enabling reliable operation in enclosed enclosures with moderate airflow. Derating curves in the datasheet confirm performance compliance across this full range.
Does LT6010AIDD#PBF support rail-to-rail input operation?
No, LT6010AIDD#PBF does not support rail-to-rail input operation. Its input common-mode range is limited to V– + 1V to V+ – 1.2V. However, its rail-to-rail output swing (within 40mV of either rail) remains fully functional. This architecture intentionally trades input range for superior DC precision - making it ideal for non-inverting configurations or buffered inverting topologies where inputs remain within the specified common-mode window.
How does the shutdown feature of LT6010AIDD#PBF behave during operation?
When the SHDN pin is pulled ≥2.0V above V–, LT6010AIDD#PBF reduces supply current to 12µA while keeping inputs electrically connected to the external circuit. The output enters high-impedance state only after internal biasing collapses - meaning it cannot isolate inputs from outputs. Therefore, LT6010AIDD#PBF shutdown is appropriate for power gating but not for analog multiplexing or channel isolation.
Can LT6010AIDD#PBF drive capacitive loads, and what is the limit?
Yes, LT6010AIDD#PBF can directly drive capacitive loads up to 500pF in unity-gain configuration without oscillation or peaking. For loads exceeding 500pF, adding a small series resistor (e.g., 10–50Ω) between the output and the capacitor restores stability. This capability simplifies anti-aliasing filter design and eliminates need for external isolation buffers in many sensor interface applications.
What is the input protection scheme implemented in LT6010AIDD#PBF?
LT6010AIDD#PBF incorporates robust input protection consisting of 500Ω series resistors on both inputs plus back-to-back diodes to V+ and V–. This limits differential input current to ≤10mA for up to 10V differential voltage, satisfying IEC 61000-4-5 surge immunity requirements at board level. External series resistors are only needed if differential transients exceed 10V - for example, 1kΩ resistors enable safe operation up to 30V differential.
