Product details
Overview
LT6010IDD#PBF from Analog Devices (formerly Linear Technology) is a single, rail-to-rail output precision operational amplifier optimized for low-noise, low-input-bias-current, and ultra-low-power operation in battery-powered and high-accuracy sensor signal conditioning. It delivers 35µV max input offset voltage, 110pA max input bias current, 135µA supply current at 5V, 14nV/√Hz input voltage noise, and operates from 2.7V to ±18V supplies - enabling use in thermocouple amplifiers, precision photodiode front-ends, and instrumentation systems.
For engineers reviewing the LT6010IDD#PBF datasheet, LT6010IDD#PBF pinout, LT6010IDD#PBF application, or LT6010IDD#PBF equivalent, key selection considerations include its guaranteed –40°C to 85°C industrial temperature range, DFN-8 (3mm × 3mm) package with exposed thermal pad, shutdown functionality reducing supply current to 12µA, and verified rail-to-rail output swing within 40mV of either rail.
Technical Context
The LT6010IDD#PBF employs a proprietary input stage with on-chip bias current cancellation, achieving sub-110pA input bias current without requiring matched external resistors. Its input offset voltage is laser-trimmed at wafer level, ensuring ≤35µV max over 0°C to 70°C and ≤80µV max over –40°C to 85°C for the I-grade variant.
It integrates internal 500Ω series input resistors and back-to-back diodes for ±10V differential input protection, supports capacitive loads up to 500pF in unity gain, and features a dedicated SHDN pin that disables the amplifier core while maintaining input/output continuity - making it unsuitable for multiplexing but ideal for power-gated precision stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ≤80 µV max over –40°C to 85°C - enables direct DC-coupled measurement of sub-mV signals without calibration drift. |
| Input Bias Current | ≤110 pA max - preserves accuracy with high-impedance sources like photodiodes or RTDs without guard-ring complexity. |
| Supply Current (Active) | 135 µA at 5V - allows continuous operation in multi-year battery-powered nodes (e.g., wireless sensor transmitters). |
| Supply Current (Shutdown) | 12 µA - reduces standby power by >90%, critical for duty-cycled precision acquisition systems. |
| Input Voltage Noise | 14 nV/√Hz at 1 kHz - dominates system noise only when source impedance <20 kΩ, supporting low-noise transimpedance designs. |
| Rail-to-Rail Output Swing | Within 40 mV of V+ and V– at no load - maximizes dynamic range in single-supply 3.3V or dual ±5V systems. |
| Common-Mode Input Range | V– + 1V to V+ – 1.2V - requires careful biasing in non-inverting configurations but avoids phase reversal. |
Pinout & Package
LT6010IDD#PBF is housed in an 8-lead plastic DFN package (3mm × 3mm), JEDEC MO-229 variation, with exposed thermal pad internally connected to V–. PCB connection to the pad is optional but recommended for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5 | NULL | No internal connection; must be left unconnected or tied to ground per layout best practice. |
| 2 | –IN | Inverting input terminal; protected by 500Ω series resistor and back-to-back diodes. |
| 3 | +IN | Non-inverting input terminal; same protection as –IN; common-mode range limited to V– + 1V to V+ – 1.2V. |
| 4 | V– | Negative supply rail; exposed thermal pad is internally bonded to this pin. |
| 6 | V+ | Positive supply rail; supports operation from 2.7V single supply up to ±18V dual supply. |
| 7 | OUT | Amplifier output; rail-to-rail swing capability enables full utilization of supply headroom. |
| 8 | SHDN | Shutdown control; < V– + 0.2V = active, ≥ V– + 2.0V = shutdown (12 µA IQ). |
Key Features
| Feature | Design Value |
|---|---|
| Laser-trimmed input offset | Ensures ≤35 µV max at 25°C and ≤80 µV max across –40°C to 85°C, eliminating need for external nulling in most applications. |
| On-chip bias current cancellation | Delivers ≤110 pA max input bias current without external balancing, preserving gain accuracy with MΩ-range feedback networks. |
| Internal input protection | 500Ω series resistors + back-to-back diodes limit differential input current to ≤10 mA at ±10V, reducing external protection component count. |
| Thermally enhanced DFN package | 3mm × 3mm footprint with exposed V– pad achieves θJA = 160°C/W, enabling stable operation at 125°C junction temperature. |
| Shutdown mode with fast enable | 25 µs turn-on/turn-off time and 12 µA shutdown current support microsecond-level power gating in synchronized data acquisition. |

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 | Lower offset (10 µV max), higher supply current (17 µA), no shutdown, SOT-23-5 package. | Lacks shutdown and thermal performance for extended industrial temperature logging; better for space-constrained, always-on low-offset apps. | Choose OPA333AIDBVR when absolute lowest offset is required and shutdown is unnecessary; avoid for battery lifetime-critical designs. |
| ADA4522-1ARMZ | Zero-drift architecture, 2.5 µV max offset, 1.2 µV/°C max drift, 750 µA supply current, SOIC-8 package. | Superior drift performance but 5.5× higher quiescent current limits use in multi-year battery systems. | Choose ADA4522-1ARMZ for ultra-stable DC measurements where power is not constrained; avoid when <200 µA active current is mandatory. |
Compared with OPA333AIDBVR and ADA4522-1ARMZ, LT6010IDD#PBF uniquely balances sub-110pA input bias, 135 µA supply current, integrated shutdown, and –40°C to 85°C guaranteed operation - making it optimal for precision, low-power, thermally demanding sensor interfaces where zero-drift isn't required but picoamp input fidelity is.

FAQ
What is the maximum junction temperature rating for LT6010IDD#PBF?
The LT6010IDD#PBF has a maximum junction temperature (TJMAX) of 125°C, as specified in the Absolute Maximum Ratings table. This is enabled by its DFN-8 package with exposed thermal pad connected to V–, yielding a thermal resistance θJA of 160°C/W under standard PCB conditions. Derating is required above 85°C ambient to maintain reliability.
Does LT6010IDD#PBF support true rail-to-rail input operation?
No, the LT6010IDD#PBF does not support rail-to-rail input operation. Its input common-mode voltage range is limited to V– + 1V to V+ – 1.2V. Exceeding this range causes gain collapse but no phase reversal. The "rail-to-rail" designation applies only to the output swing, which reaches within 40mV of both supply rails.
Can LT6010IDD#PBF drive capacitive loads, and what is the limit?
Yes, the LT6010IDD#PBF can drive capacitive loads up to 500 pF in unity-gain configuration. Stability improves with increasing closed-loop gain. For loads exceeding 500 pF, adding a small series resistor (e.g., 10–50 Ω) between the output and the capacitor restores phase margin without degrading DC accuracy.
How does the SHDN pin function, and is the output isolated during shutdown?
The SHDN pin disables the LT6010IDD#PBF's amplifier core when biased ≥2.0V above V–, reducing supply current to 12 µA. However, the output is not isolated from the inputs during shutdown - the internal input stage remains conductive. Therefore, LT6010IDD#PBF cannot be used for analog multiplexing; it is intended solely for power conservation in signal chains.
What is the guaranteed input offset voltage specification for LT6010IDD#PBF over temperature?
For the LT6010IDD#PBF (I-grade), the input offset voltage is guaranteed ≤80 µV maximum over the full –40°C to 85°C operating temperature range. At 25°C, it is ≤35 µV max. This is explicitly stated in the Electrical Characteristics table under "LT6010DD" and "LT6010IDD" rows with "TA = –40°C to 85°C" condition.
