Product details
Overview
LTC6262HMS8#PBF from Analog Devices is a dual, rail-to-rail input/output, 30MHz gain-bandwidth, micropower operational amplifier in an 8-lead MSOP package, operating from 1.8V to 5.25V supply, consuming only 240µA per amplifier, and featuring 400µV max offset voltage - ideal for precision signal conditioning in battery-powered instrumentation and automotive sensor interfaces.
For engineers reviewing the LTC6262HMS8#PBF datasheet, LTC6262HMS8#PBF pinout, LTC6262HMS8#PBF application, or LTC6262HMS8#PBF equivalent, key selection criteria include its 125°C high-temp grade, shutdown capability (10µA), 1nF capacitive load drive, 100dB CMRR, and rail-to-rail I/O performance at ultra-low quiescent current.
Technical Context
The LTC6262HMS8#PBF integrates dual PNP/NPN composite input stages enabling rail-to-rail common-mode input range (–0.1V to VS + 0.1V) and seamless transition across the full supply range. Its patented bias current cancellation circuit maintains ≤100nA input bias current over 0.2V–(VS–0.2V) common-mode span.
It employs a unity-gain-stable, high-slew-rate (7V/µs) output stage with C-load compensation, delivering >±10mA output drive while maintaining stability into 1nF loads - critical for driving ADC input filters and long traces without external compensation.
Key Specifications

| Supply Current per Amp | 240µA - supports multi-channel, always-on sensing in energy-constrained systems (e.g., IoT nodes). |
| Input Offset Voltage | 400µV max - ensures <0.1% error in 4.096V full-scale 12-bit ADC front-ends without trimming. |
| CMRR | 100dB - rejects common-mode noise from noisy automotive or industrial power rails. |
| Capacitive Load Drive | 1nF - eliminates need for isolation resistors when driving ADC input capacitance (e.g., LTC2362). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADA4661-2ARZ | Higher supply current (320µA), lower GBW (12MHz), no shutdown pin | Lacks power-down capability; unsuitable for duty-cycled sensor nodes | Select when higher DC precision (125µV VOS) outweighs shutdown and bandwidth needs |

FAQ
What is the maximum capacitive load the LTC6262HMS8#PBF can drive while remaining stable?
The LTC6262HMS8#PBF is unity-gain stable and specified to drive up to 1nF capacitive loads without external compensation. This capability is verified across the full –40°C to +125°C temperature range and supports direct connection to ADC input capacitance (e.g., LTC2362) and long PCB traces. Driving >1nF may require isolation resistors or feedback network adjustments per the datasheet's Capacitive Load Handling section.
Does the LTC6262HMS8#PBF support true ground-sensing input operation?
Yes, the LTC6262HMS8#PBF supports true ground-sensing: its input common-mode range extends to V– – 0.1V, allowing operation with inputs at 0V when V– = 0V. Combined with rail-to-rail output swing to within 100mV of V–, it enables accurate measurement of signals referenced to system ground - critical for sensor interfaces like thermocouples and bridge circuits.
What is the shutdown behavior of the LTC6262HMS8#PBF outputs?
When the SHDN pin is pulled low (<0.6V relative to V–), both amplifier outputs enter a high-impedance state. The LTC6262HMS8#PBF draws ≤10µA total supply current in this mode. Outputs remain floating - no internal pull-up/down - so external biasing or clamping may be required if connected to downstream high-impedance nodes.
Can the LTC6262HMS8#PBF operate from a 1.8V single supply?
Yes, the LTC6262HMS8#PBF is fully specified for 1.8V to 5.25V single-supply operation. At 1.8V, it delivers 28MHz GBW, 6.5V/µs slew rate, and maintains rail-to-rail input/output swing - enabling precision analog signal conditioning in coin-cell and energy-harvesting applications where supply headroom is minimal.
How does the input bias current of the LTC6262HMS8#PBF vary with common-mode voltage?
The LTC6262HMS8#PBF uses active bias current cancellation. Input bias current remains ≤100nA over the common-mode range of 0.2V above V– to 0.2V below V+, but increases beyond that region due to PNP/NPN input stage transition. At VCM = V– + 0.3V or VCM = V+ – 0.3V, typical IB is ±60nA; at extremes (e.g., VCM = V– or VCM = V+), IB rises to ±150nA - a key consideration for high-impedance source interfacing.
