Analog Devices Inc. LT6023HDD-1#PBF

Overview

LT6023HDD-1#PBF from Analog Devices (formerly Linear Technology) is a dual, micropower, precision rail-to-rail output operational amplifier with integrated shutdown control. It delivers 1.4V/µs slew rate at only 20µA per amplifier, supports ±13.6V input range in multiplexer buffer applications, and operates across –40°C to 125°C in a 10-lead 3mm × 3mm DFN package.

For engineers reviewing the LT6023HDD-1#PBF datasheet, LT6023HDD-1#PBF pinout, LT6023HDD-1#PBF application, or LT6023HDD-1#PBF equivalent, key selection considerations include its shutdown current of ≤3.2µA at 125°C, 30µV max input offset voltage, rail-to-rail output swing within 100mV of rails, 40kHz gain-bandwidth product, and guaranteed operation down to 3V supply.

Technical Context

The LT6023HDD-1#PBF implements a proprietary input stage using complementary NPN/PNP differential pairs to maintain high dynamic input impedance during large input transients (up to ±5V), eliminating phase inversion and enabling robust MUX buffering. Its enhanced slew rate architecture achieves 1.4V/µs without compromising precision specs like offset drift (±0.9µV/°C) or settling time (132µs to 0.0015% for 10V step).

Unlike standard micropower op-amps, it integrates EN and DGND pins for precise shutdown control across single- and split-supply configurations - EN threshold is referenced to DGND (0.8V low / 1.7V high), and DGND must be held between V– and V+–3V. Shutdown recovery time is 480µs, supporting duty-cycled sensor node operation.

Key Specifications

Pinout & Package

LT6023HDD-1#PBF is housed in a 10-lead 3mm × 3mm plastic DFN package with exposed thermal pad connected to V–. Pin 1 is marked by top-side dot; exposed pad (Pin 11) is optional PCB connection point for thermal enhancement and ground referencing.

FAQ

What is the maximum supply voltage for LT6023HDD-1#PBF?

The absolute maximum total supply voltage (V+ to V–) for LT6023HDD-1#PBF is 36V. Operation is specified from 3V to 30V total supply, with guaranteed performance across the full –40°C to 125°C temperature range. Exceeding 36V risks permanent damage per Absolute Maximum Ratings.

Does LT6023HDD-1#PBF support true rail-to-rail input operation?

No - LT6023HDD-1#PBF has rail-to-rail *output* capability but its input common-mode range is limited to V– + 1.2V to V+ – 1.4V. However, its proprietary input stage maintains high dynamic impedance during large transients, and many inverting/noninverting configurations achieve system-level rail-to-rail functionality without requiring RRI inputs.

How does the EN pin function on LT6023HDD-1#PBF?

The EN pin on LT6023HDD-1#PBF is an active-high enable input referenced to the DGND pin. It enters shutdown when pulled below 0.8V relative to DGND and activates when driven above 1.7V. DGND must be externally tied to a stable node between V– and V+–3V - enabling flexible control from 3V logic, microcontrollers, or split-supply systems.

What is the typical settling time for LT6023HDD-1#PBF at 0.0015% accuracy?

LT6023HDD-1#PBF settles to 0.0015% of final value in 132µs for a 10V output step (AV = 1). This performance is maintained across temperature - 124µs at –40°C to 125°C - making it suitable for high-precision, time-critical acquisition in multiplexed data loggers and automated test equipment.

Can LT6023HDD-1#PBF drive capacitive loads?

Yes - LT6023HDD-1#PBF can directly drive up to 100pF in unity-gain configuration. Capacitive load drive capability increases with closed-loop gain; adding a small series resistor (e.g., 10–50Ω) between output and load further improves stability with larger capacitances, such as ADC input sampling capacitors or long PCB traces.
