Product details
Overview
LTC6262IMS#TRPBF from Analog Devices is a dual, rail-to-rail input/output, low-noise, micropower operational amplifier in a 10-lead MSOP package. It delivers 30MHz gain-bandwidth, 7V/µs slew rate, and 240µA supply current per amplifier across 1.8V–5.25V supply range, with shutdown capability reducing current to ≤10µA. It drives up to 1nF capacitive loads and supports precision signal conditioning in battery-powered instrumentation.
For engineers reviewing the LTC6262IMS#TRPBF datasheet, LTC6262IMS#TRPBF pinout, LTC6262IMS#TRPBF application, or LTC6262IMS#TRPBF equivalent, key selection criteria include its 400µV max offset voltage, 100nA max input bias current, 100dB CMRR, –40°C to 125°C H-grade temperature range, and active-low SHDN functionality in the MSOP-10 footprint.
Technical Context
The LTC6262IMS#TRPBF employs a composite PNP/NPN input stage that enables rail-to-rail common-mode input (–0.1V to VSUPPLY + 0.1V) and maintains low bias current (≤100nA) over 0.2V–(VSUPPLY–0.2V). Its patented output buffer uses a common-emitter topology for true rail-to-rail output swing (≤130mV from rails at 1mA).
It integrates internal bias current cancellation circuitry and features unity-gain stability with ≥1nF capacitive loads. The shutdown pin (SHDN) asserts at ≤0.6V above V–, disabling both amplifiers and placing outputs in high-impedance state while drawing ≤10µA total supply current.

FAQ
What is the maximum capacitive load the LTC6262IMS#TRPBF can drive while maintaining stability?
The LTC6262IMS#TRPBF is unity-gain stable and characterized to drive up to 1nF capacitive loads without oscillation or excessive overshoot. This capability eliminates external isolation resistors when interfacing with SAR ADCs like the LTC2362 or long PCB traces, preserving signal integrity and simplifying layout. Performance is verified across –40°C to 125°C and 1.8V–5.25V supply range.
Does the LTC6262IMS#TRPBF support true rail-to-rail input and output operation?
Yes-the LTC6262IMS#TRPBF supports rail-to-rail input common-mode range from V– –0.1V to V+ +0.1V and rail-to-rail output swing within 130mV of either rail at 1mA load. This enables full-scale signal utilization in 1.8V single-supply systems, such as battery-powered sensor nodes, without level-shifting circuitry.
How does the shutdown feature of the LTC6262IMS#TRPBF operate?
The LTC6262IMS#TRPBF's SHDN pin is active-low: asserting ≤0.6V above V– disables both amplifiers, reduces total supply current to ≤10µA, and places both outputs in high-impedance state. The pin is internally pulled up to V+, so leaving it unconnected keeps the device enabled. Turn-on/off times are 15µs and 6µs respectively at 5V supply.
What is the guaranteed input offset voltage specification for the LTC6262IMS#TRPBF over temperature?
The LTC6262IMS#TRPBF guarantees ±400µV maximum input offset voltage over the full –40°C to 125°C operating temperature range. This specification is measured at VSUPPLY = 5V and applies across the entire common-mode input range, ensuring consistent DC accuracy in automotive and industrial environments without external trimming.
Can the LTC6262IMS#TRPBF operate from a 1.8V supply while maintaining full AC performance?
Yes-the LTC6262IMS#TRPBF is fully specified at 1.8V supply, delivering 28MHz gain-bandwidth, 6.5V/µs slew rate, and 100dB CMRR over –40°C to 125°C. Its 240µA supply current remains stable across voltage range, making it ideal for energy-harvesting and coin-cell applications where supply headroom is constrained.
