Product details
Overview
LT6010CS8#PBF from Analog Devices (formerly Linear Technology) is a precision rail-to-rail output operational amplifier optimized for low-noise, low-power, high-accuracy signal conditioning in battery-powered and sensor interface applications. 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 LT6010CS8#PBF datasheet, LT6010CS8#PBF pinout, LT6010CS8#PBF application, or LT6010CS8#PBF equivalent, key selection criteria include its guaranteed 0.8µV/°C VOS drift over –40°C to 85°C, shutdown mode reducing current to 12µA, and SO-8 package compatibility with precision thermocouple and RTD measurement circuits requiring stable DC accuracy.
Technical Context
The LT6010CS8#PBF employs a proprietary input stage with on-chip trimming to achieve sub-35µV offset and <0.8µV/°C drift across temperature. Its 120dB minimum open-loop gain and 107dB CMRR ensure stability in high-gain instrumentation configurations, while internal 500Ω series input resistors and back-to-back diodes provide robust ±10V differential input protection.
It operates from single 2.7V or dual ±1.35V supplies, supports rail-to-rail output swing within 40mV of either rail, and integrates a dedicated SHDN pin that disables the amplifier core-reducing supply current to 12µA-without isolating inputs, making it unsuitable for multiplexing but ideal for power-gated sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | Max 35µV at 0°C–70°C; ensures ≤0.35mV error in 10V full-scale systems without calibration. |
| Input Bias Current | Max ±110pA; enables use with >10GΩ source impedances (e.g., photodiode, high-value RTD bridges) without significant current-induced offset. |
| Supply Current | 135µA active / 12µA shutdown; allows decade-level battery life extension in intermittent-sampling sensor nodes. |
| Input Voltage Noise | 14nV/√Hz at 1kHz; dominates system noise only below ~20kΩ source impedance, preserving SNR in precision transimpedance stages. |
| Rail-to-Rail Output | Swings to within 40mV of V+ and V−; supports full dynamic range utilization in 3.3V or 5V single-supply data acquisition. |
| Gain Bandwidth | 250kHz typical; sufficient for DC–10kHz sensor signal bandwidths with ≥100dB loop gain margin. |
| CMRR | Min 107dB; rejects common-mode interference in noisy industrial environments (e.g., motor drives, PLC I/O). |
Pinout & Package
LT6010CS8#PBF is housed in an 8-lead plastic SO (narrow, 0.150") package with exposed pad internally connected to V−. Pin 1 is marked by a notch or dot; the package is RoHS-compliant and lead-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | No-connect | Internally unused; must be left floating or tied to ground per layout best practices to minimize leakage paths. |
| 2 (V+) | Positive Supply | Accepts 2.7V to +18V (single) or up to ±18V (dual); decoupling capacitor required within 1cm for stability. |
| 3 (OUT) | Amplifier Output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ≥10mA; requires series resistor for >500pF capacitive loads. |
| 4 (SHDN) | Shutdown Control | Active-low logic: ≤0.2V above V− enables operation; ≥2.0V above V− reduces supply current to 12µA. |
| 5 (NULL) | No-connect | Internally unused; same handling as Pin 1. |
| 6 (–IN) | Inverting Input | Differential input node; input bias current ≤±110pA; protected by 500Ω series resistor and clamp diodes. |
| 7 (+IN) | Non-inverting Input | Differential input node; identical protection and bias specs as –IN; common-mode range limited to V−+1V to V+–1.2V. |
| 8 (V−) | Negative Supply | Accepts 0V (single-supply) or –18V (dual); exposed pad must be soldered to PCB ground plane for thermal and EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| Trimmed Input Offset | Factory-trimmed to ≤35µV (C-grade), enabling high-accuracy DC measurements without external nulling circuitry. |
| Ultra-Low Input Bias Current | ≤±110pA maximum ensures minimal error when interfacing with high-impedance sensors like platinum RTDs or photodiodes. |
| Rail-to-Rail Output Stage | Output swings within 40mV of both rails at light loads, maximizing usable signal range in low-voltage systems (e.g., 3.3V IoT nodes). |
| Integrated Shutdown Mode | Reduces quiescent current from 135µA to 12µA via SHDN pin, supporting energy-efficient wake-up architectures in portable instrumentation. |
| Robust Input Protection | On-chip 500Ω series resistors and back-to-back diodes limit input current to ≤10mA under ±10V differential stress, 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 |
|---|---|---|---|
| OPA333AIDR | Zero-drift architecture; 0.1µV/°C max drift vs. LT6010CS8#PBF's 0.8µV/°C; higher 17µA supply current; no shutdown pin. | Better long-term drift stability for multi-year uncalibrated deployments; lacks power-gating capability for duty-cycled systems. | Select OPA333AIDR when ultra-low drift dominates over power budget and shutdown is unnecessary. |
| AD8628ARZ | Chopper-stabilized; 1µV max VOS; 1.5µV/°C max drift; 1.2mA supply current; no shutdown; SO-8 package. | Superior initial offset for factory-calibrated systems; significantly higher quiescent current limits battery life in portable designs. | Select AD8628ARZ when lowest possible initial offset is critical and power consumption is secondary. |
Compared with OPA333AIDR and AD8628ARZ, the LT6010CS8#PBF uniquely balances sub-35µV offset, ultra-low 135µA supply current, integrated shutdown, and robust ±10V input protection-making it optimal for cost-sensitive, battery-operated precision sensor interfaces where moderate drift is acceptable.

FAQ
What is the maximum supply voltage range supported by the LT6010CS8#PBF?
The LT6010CS8#PBF operates from a total supply voltage (V+ to V−) of up to 40V, supporting single supplies from 2.7V to 36V or dual supplies from ±1.35V to ±18V. This wide range allows direct integration into both low-voltage battery systems and industrial ±15V legacy platforms without level-shifting circuitry. The LT6010CS8#PBF maintains specified performance across this entire range.
Does the LT6010CS8#PBF have rail-to-rail input capability?
No, the LT6010CS8#PBF features rail-to-rail *output* swing but not rail-to-rail *input*. Its input common-mode voltage range is limited to V− + 1V to V+ − 1.2V. Exceeding this range causes gain collapse without phase reversal. For applications requiring full rail-to-rail input, designers should consider alternatives like the LT6015 or LTC6241, while retaining the LT6010CS8#PBF for output-stage optimization.
How does the shutdown function work on the LT6010CS8#PBF?
The LT6010CS8#PBF enters shutdown when the SHDN pin voltage is ≥2.0V above V−, reducing supply current to 12µA. When SHDN ≤ V− + 0.2V, the device operates normally. An internal 85kΩ pull-down ensures default operation if SHDN is left unconnected. Critically, the output remains electrically connected to inputs during shutdown, so the LT6010CS8#PBF cannot be used for analog multiplexing.
What is the guaranteed input offset voltage drift specification for the LT6010CS8#PBF over temperature?
The LT6010CS8#PBF has a guaranteed maximum input offset voltage drift of 0.8µV/°C over the full –40°C to +85°C operating temperature range. This drift value applies to the C-grade (LT6010CS8) and A-grade (LT6010ACS8) variants. The drift is measured and specified under conditions where VOS itself is guaranteed ≤35µV (A-grade) or ≤55µV (C-grade) across the same temperature span.
Can the LT6010CS8#PBF drive capacitive loads, and what is the recommended approach?
Yes, the LT6010CS8#PBF can drive up to 500pF in unity-gain configurations. For larger capacitive loads, adding a small series resistor (e.g., 10–50Ω) between the output and the load improves phase margin and prevents peaking or oscillation. Performance degrades gradually beyond 500pF in G=1; however, closed-loop gain ≥10 increases capacitive drive capability substantially due to improved loop gain at high frequencies.
