Analog Devices Inc. LT6010CDD#PBF

Overview

LT6010CDD#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 applications. 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 - ideal for thermocouple amplification and battery-powered instrumentation.

For engineers reviewing the LT6010CDD#PBF datasheet, LT6010CDD#PBF pinout, LT6010CDD#PBF application, or LT6010CDD#PBF equivalent, key selection considerations include its DFN-8 (3mm × 3mm) package, shutdown functionality (12µA quiescent), –40°C to 85°C industrial temperature range, and verified performance in high-impedance sensor interfaces requiring sub-100µV offset stability.

Technical Context

The LT6010CDD#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 initial offset and ≤0.8µV/°C drift over the full operating range, supporting long-term accuracy in precision measurement circuits.

It integrates a dedicated SHDN pin that disables the amplifier core while maintaining input continuity, reducing supply current to 12µA without disconnecting inputs - a critical feature for power-gated sensor front-ends where signal path integrity must persist during sleep states.

Key Specifications

Pinout & Package

FAQ

What is the maximum input common-mode voltage range for LT6010CDD#PBF?

The LT6010CDD#PBF input common-mode voltage range is specified as V– + 1V to V+ – 1.2V under guaranteed conditions. For example, with ±5V supplies, the valid input range is –4V to +3.8V. Exceeding this range causes gain collapse but no phase reversal. This limitation is inherent to its bipolar input stage and must be respected in non-inverting configurations where input voltage tracks output swing.

Does LT6010CDD#PBF support true rail-to-rail input operation?

No, the LT6010CDD#PBF does not support rail-to-rail input operation. Its input stage is limited to V– + 1V to V+ – 1.2V, as confirmed in the Electrical Characteristics table and Applications Information section. While its output swings rail-to-rail, the input common-mode range excludes the supply rails - making it unsuitable for applications requiring input signals near V+ or V– without level-shifting circuitry.

How does the shutdown function behave in LT6010CDD#PBF regarding input isolation?

The LT6010CDD#PBF shutdown function reduces supply current to ~12µA but does not isolate the inputs from the output or internal nodes. The –IN and +IN terminals remain electrically connected to the internal amplifier core even in shutdown mode. Therefore, LT6010CDD#PBF cannot be used for analog multiplexing or signal blocking - it is intended solely for power conservation while preserving signal path readiness for fast wake-up.

What is the recommended PCB layout practice for minimizing thermocouple-induced offset in LT6010CDD#PBF circuits?

To minimize thermocouple-induced offset in LT6010CDD#PBF circuits, keep +IN and –IN traces short, symmetrical, and routed close together on the same PCB layer - avoiding vias or dissimilar metal junctions near the inputs. Place the device away from heat sources (e.g., regulators, power inductors), and use a guard ring around both inputs tied to the common-mode voltage. These practices mitigate thermal gradients that generate µV-level parasitic voltages, preserving the amplifier's specified 35µV offset performance.

Can LT6010CDD#PBF drive capacitive loads, and what is the maximum stable value?

Yes, the LT6010CDD#PBF can drive capacitive loads up to 500pF in unity-gain configuration, as verified in the Typical Performance Characteristics. Stability improves with increasing closed-loop gain; for gains ≥10, it supports >1nF loads. When driving >500pF, adding a small series resistor (10–50Ω) between the output and load restores phase margin without degrading DC accuracy - a technique validated in the Capacitive Loads application note section.
