Product details
Overview
LT6010AIS8#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 battery-powered instrumentation. It delivers 35µV max input offset voltage, 110pA max input bias current, 135µA supply current, 14nV/√Hz input voltage noise density, and rail-to-rail output swing from 2.7V to ±18V supplies.
For engineers reviewing the LT6010AIS8#PBF datasheet, LT6010AIS8#PBF pinout, LT6010AIS8#PBF application, or LT6010AIS8#PBF equivalent, key selection criteria include guaranteed –40°C to 85°C operation with A-grade precision, shutdown mode reducing supply current to 12µA, and SO-8 package compatibility with legacy layouts requiring minimal redesign effort.
Technical Context
The LT6010AIS8#PBF employs a proprietary input stage with on-chip trimming to achieve sub-35µV offset and 0.8µV/°C max drift across its full operating temperature range. Its input bias current is actively cancelled, enabling high-impedance sensor interfacing without external balancing resistors.
It features internal 500Ω series input protection resistors and back-to-back diodes, allowing safe operation with up to 10V differential input voltage. The SHDN pin controls power-down with 25µs turn-on/off timing and an internal 85kΩ pull-down resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 35µV at 0°C to 70°C; ensures <100µV total error in precision DC gain stages without calibration. |
| Input Bias Current | Max ±110pA at 0°C to 70°C; enables stable operation with >10GΩ feedback networks and high-Z sensors. |
| Supply Current | 135µA active / 12µA shutdown; supports multi-year battery life in portable instrumentation. |
| Input Voltage Noise | 14nV/√Hz at 1kHz; dominates system noise only below ~20kΩ source impedance. |
| Rail-to-Rail Output | Swings within 40mV of either rail; delivers full dynamic range in single-supply 3.3V or dual ±5V systems. |
| Common-Mode Range | V– + 1V to V+ – 1.2V; defines usable input voltage window independent of rail-to-rail output capability. |
| Gain Bandwidth Product | 250kHz typical; supports stable closed-loop gains up to ~25 at 10kHz for sensor signal conditioning. |
Pinout & Package
LT6010AIS8#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; exposed pad is not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | No-connect terminal | Internally unconnected; must be left floating or tied to ground per layout best practices. |
| 2 (V+) | Positive supply rail | Accepts 2.7V to +18V; requires local 0.1µF bypass capacitor to minimize PSRR degradation. |
| 3 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ≥10mA into resistive loads. |
| 4 (SHDN) | Shutdown control input | Pull ≤0.2V above V– to enable; pull ≥2V above V– to reduce supply current to 12µA. |
| 5 (NULL) | No-connect terminal | Internally unconnected; must be left floating or tied to ground per layout best practices. |
| 6 (–IN) | Inverting input | High-impedance node; sensitive to leakage and thermal gradients-requires guard ring and symmetric layout. |
| 7 (+IN) | Non-inverting input | High-impedance node; matched to –IN for common-mode rejection; avoid unequal trace lengths. |
| 8 (V–) | Negative supply rail | Accepts 0V (single supply) or –18V; serves as reference for SHDN threshold and internal biasing. |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed input offset voltage | Guaranteed ≤35µV over 0°C to 70°C enables high-accuracy DC amplification without external nulling. |
| Ultra-low input bias current | ≤±110pA eliminates error from high-value feedback resistors and preserves photodiode linearity. |
| Rail-to-rail output swing | Output reaches within 40mV of V+ and V–, maximizing signal headroom in low-voltage systems. |
| Integrated shutdown mode | Reduces quiescent current to 12µA while retaining input connectivity-ideal for duty-cycled sensor front-ends. |
| Robust input protection | On-chip 500Ω series resistors and back-to-back diodes withstand 10V differential input without external components. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1µV/°C max drift vs. LT6010AIS8#PBF's 0.8µV/°C; higher 17µA supply current. | Better long-term drift stability but higher power; less suitable for battery-constrained designs. | Select OPA333AIDR when drift-critical DC accuracy outweighs quiescent current budget. |
| LTC2050CS8#PBF | Chopper-stabilized; 0.5µV max VOS; 1.5µA supply current; no shutdown pin. | Lower offset and power, but lacks integrated shutdown and has different noise profile (chopper ripple). | Select LTC2050CS8#PBF for ultra-low-offset, ultra-low-power applications where shutdown is implemented externally. |

FAQ
What is the maximum input differential voltage rating for LT6010AIS8#PBF?
The LT6010AIS8#PBF has an absolute maximum differential input voltage rating of 10V, enforced by internal 500Ω series resistors and back-to-back diodes. Exceeding this voltage risks exceeding the ±10mA input current limit specified in the Absolute Maximum Ratings table. For applications expecting >10V differential inputs, external series resistors must be added to limit current to ≤10mA.
Does LT6010AIS8#PBF support true rail-to-rail input operation?
No, the LT6010AIS8#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, the input stage requires at least 1V headroom from each supply rail. This is sufficient for most non-inverting and inverting configurations where input nodes remain near mid-supply.
How does the shutdown feature affect the output state of LT6010AIS8#PBF?
During shutdown, the LT6010AIS8#PBF disables its internal bias circuitry to reduce supply current to 12µA, but the output remains electrically connected to the inputs-it does not become high-impedance or disconnected. Therefore, LT6010AIS8#PBF cannot be used for analog multiplexing or output isolation; it is intended solely for power conservation in idle periods.
What is the guaranteed operating temperature range for LT6010AIS8#PBF?
The LT6010AIS8#PBF is guaranteed to meet all A-grade specifications over the full industrial temperature range of –40°C to +85°C. This includes the 35µV maximum input offset voltage, 110pA maximum input bias current, and 135µA supply current, as explicitly confirmed in the Electrical Characteristics tables under "TA = –40°C to 85°C" conditions.
Can LT6010AIS8#PBF drive capacitive loads, and what is the recommended compensation?
Yes, the LT6010AIS8#PBF can drive up to 500pF capacitive loads in unity-gain configuration. Stability improves with increasing closed-loop gain. For loads exceeding 500pF or in unity-gain applications requiring enhanced phase margin, a small series resistor (typically 10Ω–100Ω) placed between the output pin and the capacitive load is recommended to isolate the amplifier from the reactive load.
