Product details
Overview
LT6010IS8#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 low-power applications including thermocouple amplification, photodiode signal conditioning, and battery-powered instrumentation. It delivers 35µV max input offset voltage, 110pA max input bias current, 135µA supply current at 5V, 14nV/√Hz input voltage noise, and rail-to-rail output swing within 40mV of either rail.
For engineers reviewing the LT6010IS8#PBF datasheet, LT6010IS8#PBF pinout, LT6010IS8#PBF application, or LT6010IS8#PBF equivalent, key selection criteria include its guaranteed –40°C to 85°C industrial temperature range, SO-8 package compatibility, shutdown mode reducing supply current to 12µA, and precision performance under single-supply (2.7V) and dual-supply (±15V) operation.
Technical Context
The LT6010IS8#PBF employs a proprietary input stage with on-chip bias current cancellation, enabling stable picoamp-level input bias currents across temperature. Its internal trimming ensures ≤35µV offset and ≤0.8µV/°C drift over the full –40°C to 85°C range, supporting high-accuracy DC-coupled measurement systems.
It integrates a dedicated SHDN pin that disables the amplifier core while maintaining input connectivity, allowing power gating without signal path isolation. The rail-to-rail output stage uses complementary bipolar output transistors to achieve <40mV saturation voltage near both rails under light load, enabling full dynamic range utilization in low-voltage single-supply designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤35µV max (guaranteed over –40°C to 85°C); enables sub-100µV system-level DC error in precision sensor front-ends. |
| Input Bias Current | ≤110pA max (–40°C to 85°C); supports high-impedance sources like photodiodes and RTDs without significant error. |
| Supply Current | 135µA typical at 5V; allows continuous operation in multi-year battery-powered devices. |
| Input Voltage Noise | 14nV/√Hz at 1kHz; maintains signal integrity in low-level analog signal chains with source impedances <20kΩ. |
| Rail-to-Rail Output | Swings to within 40mV of V+ and V–; delivers full-scale output headroom in 3.3V or 5V single-supply systems. |
| Shutdown Current | 12µA typical; reduces quiescent power by >90% during idle periods without external circuitry. |
| CMRR | ≥107dB (–40°C to 85°C); rejects common-mode interference in noisy industrial environments. |
Pinout & Package
LT6010IS8#PBF is housed in an 8-lead plastic SO (Small Outline) package with 0.150-inch body width and standard JEDEC MS-012AC footprint. Pin 1 is marked with a notch or dot; the package is RoHS-compliant and lead-free.

| 3 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ≥10mA. |
| 4 (SHDN) | Shutdown control input | Pull ≤0.2V above V– to enable; pull ≥2.0V above V– to enter 12µA shutdown mode. |
| 5 (NULL) | No-connect terminal | Internally unconnected; must be left floating or tied to ground. |
| 6 (–IN) | Inverting input | Differential input node with 110pA max bias current; requires guarded layout for high-Z sources. |
| 7 (+IN) | Non-inverting input | Differential input node; common-mode range limited to V– + 1V to V+ – 1.2V. |
| 8 (V–) | Negative supply rail | Accepts 0V (single supply) or –18V (dual supply); underside metal pad internally connected to V–. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LT6010CS8#PBF | Same architecture but specified only from 0°C to 70°C; 55µV max offset (0°C–70°C) vs. 35µV for LT6010IS8#PBF. | Suitable for commercial-grade equipment; not rated for extended industrial temperature range. | Select LT6010IS8#PBF when guaranteed –40°C to 85°C operation and tighter offset spec are required. |
| OPA333AIDR | Zero-drift auto-zero topology; 10µV max offset, 0.02µV/°C drift, but higher 17µA supply current and 5.5V max supply. | Better DC accuracy over temperature; less suitable for >5.5V or ultra-low-power (<135µA) applications. | Choose OPA333AIDR where ultra-low drift dominates over power and voltage range constraints. |
Compared with LT6010CS8#PBF, LT6010IS8#PBF provides guaranteed industrial temperature performance and lower offset; compared with OPA333AIDR, it offers wider supply range and lower quiescent current at the expense of slightly higher drift.

FAQ
What is the maximum supply voltage rating for LT6010IS8#PBF?
The LT6010IS8#PBF has an absolute maximum total supply voltage (V+ to V–) rating of 40V. It operates over a recommended supply range of 2.7V to ±18V (i.e., up to 36V total), making it suitable for both low-voltage battery systems and higher-voltage industrial supplies. Exceeding 40V risks permanent damage.
Does LT6010IS8#PBF support true rail-to-rail input operation?
No, the LT6010IS8#PBF does not support rail-to-rail input operation. Its input common-mode voltage range is limited to V– + 1V to V+ – 1.2V. While the output swings rail-to-rail (within 40mV), the inputs require headroom. This design prioritizes precision and low bias current over input voltage range.
How does the shutdown feature of LT6010IS8#PBF behave electrically?
When the SHDN pin is pulled ≥2.0V above V–, the LT6010IS8#PBF reduces supply current to ~12µA, disabling the amplifier core. However, the output remains connected to the inputs - it is not isolated. Therefore, LT6010IS8#PBF cannot be used for analog multiplexing; it only reduces power consumption during idle periods.
What is the guaranteed input offset voltage specification for LT6010IS8#PBF over temperature?
The LT6010IS8#PBF guarantees a maximum input offset voltage of 35µV at 25°C, 60µV over 0°C to 70°C, and 75µV over the full –40°C to 85°C industrial temperature range. This graded specification reflects tested performance across conditions, with the 75µV value being the worst-case bound for end-of-life reliability in harsh environments.
Can LT6010IS8#PBF drive capacitive loads, and if so, how large?
Yes, the LT6010IS8#PBF is stable driving up to 500pF in unity-gain configuration. Stability improves with higher closed-loop gain. For loads exceeding 500pF, adding a small series resistor (e.g., 10–50Ω) between the output and the capacitive load restores phase margin without degrading DC accuracy - a key advantage in ADC interface and filtering applications.
