Analog Devices Inc. LTC6262HTS8#TRMPBF

Overview

LTC6262HTS8#TRMPBF from Analog Devices is a dual, rail-to-rail input/output, 30MHz gain-bandwidth, 240µA per amplifier operational amplifier in an 8-lead TSOT-23 package, operating from 1.8V to 5.25V supply. It delivers 7V/µs slew rate, drives up to 1nF capacitive loads, and features 400µV max offset voltage and 100dB CMRR - ideal for micropower active filters and portable instrumentation.

For engineers reviewing the LTC6262HTS8#TRMPBF datasheet, LTC6262HTS8#TRMPBF pinout, LTC6262HTS8#TRMPBF application, or LTC6262HTS8#TRMPBF equivalent, key selection criteria include its –40°C to 125°C H-grade temperature rating, shutdown capability (10µA max), low 13nV/√Hz input voltage noise, and verified rail-to-rail I/O performance across full supply range.

Technical Context

The LTC6262HTS8#TRMPBF uses a dual-input-stage architecture with PNP and NPN differential pairs that auto-switch based on common-mode voltage, enabling true rail-to-rail input operation from V– – 0.1V to V+ + 0.1V. Its patented bias current cancellation maintains ≤100nA max input bias current over 0.2V to (V+ – 0.2V) common-mode range.

It integrates a high-slew-rate buffer and output stage capable of ±10mA drive while maintaining unity-gain stability into 1nF loads. Shutdown control is active-low with 0.6V threshold referenced to V–, placing output in high-impedance state and reducing supply current to ≤10µA.

FAQ

What is the maximum capacitive load the LTC6262HTS8#TRMPBF can drive while remaining unity-gain stable?

The LTC6262HTS8#TRMPBF is unity-gain stable driving up to 1nF capacitive loads, as confirmed in the datasheet's Typical Performance Characteristics (Figure 28). This capability eliminates the need for isolation resistors when interfacing directly with ADC input capacitance or long PCB traces, preserving signal integrity and THD+N performance in applications like SAR ADC drivers.

Does the LTC6262HTS8#TRMPBF support true rail-to-rail input operation below the negative supply rail?

Yes, the LTC6262HTS8#TRMPBF accepts input voltages down to V– – 0.1V, enabling true ground-sensing in single-supply configurations. Its dual-input-stage architecture (PNP/NPN) ensures continuous operation across the full range, and internal ESD diodes limit differential input voltage to prevent damage - critical for interfacing with sensors referenced to chassis ground.

What is the shutdown current specification for the LTC6262HTS8#TRMPBF, and how is the shutdown pin controlled?

The LTC6262HTS8#TRMPBF draws ≤10µA total supply current in shutdown mode. The SHDN pin is active-low with a threshold of 0.6V above V–; pulling SHDN ≤0.6V disables both amplifiers and places their outputs in high-impedance state. When left unconnected, internal pull-up keeps the device enabled - no external pull-up required.

Can the LTC6262HTS8#TRMPBF operate from a 1.8V single supply, and what are the output swing limitations at this voltage?

Yes, the LTC6262HTS8#TRMPBF operates from 1.8V to 5.25V. At 1.8V supply, its output swings to within 100mV of V– and 170mV of V+ at 1mA load (per datasheet Table on page 5), enabling effective use in ultra-low-voltage IoT nodes. Rail-to-rail output behavior is maintained, but absolute swing margins scale linearly with supply voltage.

How does the input bias current of the LTC6262HTS8#TRMPBF vary with common-mode voltage, and why does it matter for high-impedance sources?

The LTC6262HTS8#TRMPBF uses bias current cancellation, achieving ≤100nA max input bias current when common-mode voltage is between 0.2V above V– and 0.2V below V+. Outside this range, bias current rises - potentially introducing >1mV error with 10MΩ source impedances. This behavior is critical when selecting feedback networks or interfacing with pH electrodes or photodiode transimpedance stages.
