LT1636CDD#PBF

Instrumentation, Op Amps, Buffer Amps Overview

The LT1636CDD#PBF is a single-channel, micropower rail-to-rail input and output operational amplifier manufactured by Analog Devices Inc. It operates on total supplies from 2.7V to 44V with a quiescent current of 50µA. Key electrical parameters include a gain-bandwidth product of 220kHz, a slew rate of 0.07V/µs, and an input offset voltage maximum of 425µV at 25°C. The device features Over-The-Top operation, allowing the common mode input voltage to extend 44V above VEE. It provides 18mA output drive capability and includes an output shutdown function that reduces supply current to 4µA.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Over-The-Top input stage allows common mode voltage to exceed the positive supply rail by up to 44V.
• Rail-to-rail input and output capabilities ensure full signal swing across the supply range.
• Micropower consumption with 50µA typical quiescent current and 4µA in shutdown mode.
• Integrated reverse battery protection up to 27V and input fault protection below the negative supply.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery or solar-powered systems
• Portable instrumentation
• Sensor conditioning circuits
• Supply current sensing applications

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific temperature grade suffix (C for -40°C to 85°C) against application requirements. Confirm the DFN package dimensions match the PCB footprint design. Ensure the datasheet revision matches the design documentation. Check for any lead-free or RoHS compliance markings if required by regulatory standards. Validate pinout compatibility during integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high common mode voltage tolerance above the positive rail is required alongside low power consumption. The rail-to-rail I/O makes it suitable for single-supply applications with limited headroom. Consider the 18mA output drive for moderate load requirements. The shutdown feature aids in power management for battery-operated devices requiring extended standby times.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LT1636 family of precision operational amplifiers. It shares architectural similarities with other micropower op amps but distinguishes itself through the unique Over-The-Top input stage. The DD package variant offers a compact 3mm x 3mm form factor suitable for space-constrained designs compared to larger SOIC or PDIP options.
