Analog Devices Inc. LT6000CDCB#TRMPBF

Overview

LT6000CDCB#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, precision rail-to-rail input/output operational amplifier optimized for micropower, low-voltage operation. It delivers 13 µA supply current per amplifier, 600 µV max input offset voltage, and full functionality down to 1.8 V supply - enabling use in battery-powered gas sensing front-ends and portable instrumentation where quiescent power and signal fidelity are critical.

For engineers reviewing the LT6000CDCB#TRMPBF datasheet, LT6000CDCB#TRMPBF pinout, LT6000CDCB#TRMPBF application, or LT6000CDCB#TRMPBF equivalent, key selection criteria include guaranteed 1.8 V operation, shutdown capability (1.5 µA max), DFN-6 package footprint, and rail-to-rail performance across –40°C to 85°C without derating.

Technical Context

The LT6000CDCB#TRMPBF employs a dual-input-stage architecture: a PNP pair active from V– to ~1 V below V+, and an NPN pair active near V+, enabling true rail-to-rail input with <400 µV typical CMRR-induced offset variation. Its folded-cascode second stage and complementary drive output stage support rail-to-rail output swing within 30 mV of either rail under no-load conditions.

Shutdown is implemented via a dedicated SHDN pin that places the amplifier in high-impedance state with ≤1.5 µA total supply current when pulled ≤0.3 V above V–. The device is fully specified at both 1.8 V and 5 V supplies, with gain bandwidth product (32–50 kHz) and slew rate (9–15 V/ms) characterized over temperature and supply voltage.

FAQ

What is the minimum supply voltage for reliable operation of the LT6000CDCB#TRMPBF?

The LT6000CDCB#TRMPBF is fully specified and guaranteed functional down to 1.8 V supply across –40°C to 85°C. Electrical characteristics including input offset voltage, gain bandwidth, and rail-to-rail output swing are tested and validated at 1.8 V, enabling direct use with single-cell lithium or alkaline batteries without regulation. Operation below 1.8 V is not characterized.

Does the LT6000CDCB#TRMPBF support true rail-to-rail input and output?

Yes, the LT6000CDCB#TRMPBF supports true rail-to-rail input (common-mode range from V– to V+) and output (swing within 30 mV of either rail under no-load conditions). This is achieved via dual-input-stage architecture and complementary output drive - confirmed in the datasheet's "Rail-to-Rail Characteristics" section and validated across temperature and supply voltage.

How does the shutdown feature of the LT6000CDCB#TRMPBF work, and what is its leakage behavior?

The LT6000CDCB#TRMPBF enters shutdown when the SHDN pin is pulled ≤0.3 V above V–, reducing total supply current to ≤1.5 µA. In shutdown, the output becomes high-impedance with ≤20 nA leakage (V– ≤ V_OUT ≤ V+). The SHDN pin draws ≤30 nA when high, allowing direct GPIO control without additional level-shifting circuitry.

What package type and dimensions does the LT6000CDCB#TRMPBF use?

The LT6000CDCB#TRMPBF uses a 6-lead plastic DFN package (DCB), measuring 2.0 mm × 3.0 mm × 0.75 mm with an exposed thermal pad connected to V–. Pin 1 is marked by a notch and located at the top-left corner; the package complies with JEDEC MO-229 variation and is RoHS-compliant and lead-free.

Is the LT6000CDCB#TRMPBF suitable for driving capacitive loads, and what is its stability behavior?

The LT6000CDCB#TRMPBF is unity-gain stable and can drive up to 100 pF capacitive loads with <5% overshoot (per Figure 23 in datasheet). For larger loads, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended. Phase margin remains >60° across temperature and supply voltage, ensuring robust stability in sensor interface circuits.
