Analog Devices Inc. LTC6244HMS8#TRPBF

Overview

LTC6244HMS8#TRPBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail output, low-noise CMOS operational amplifier optimized for high-speed photodiode and transducer signal conditioning. It delivers 50MHz gain bandwidth, 40V/μs slew rate, 1pA input bias current, 1.5μV_P-P 0.1Hz–10Hz noise, and operates from 2.8V to 6V supply - enabling precision amplification in low-voltage, high-impedance sensor front-ends.

For engineers reviewing the LTC6244HMS8#TRPBF datasheet, LTC6244HMS8#TRPBF pinout, LTC6244HMS8#TRPBF application, or LTC6244HMS8#TRPBF equivalent, this page provides verified package mapping (8-pin MSOP), temperature-rated performance (–40°C to 125°C), rail-to-rail output swing (±35mV of rails), input common-mode range to V–, and confirmed low-noise design value for photodiode and medical instrumentation use cases.

Technical Context

The LTC6244HMS8#TRPBF employs a folded-cascode input stage with laser-trimmed MOSFETs to achieve ultra-low input bias current and low offset voltage drift (2.5μV/°C max). Its differential drive generator enables true rail-to-rail output swing while maintaining stability at unity gain.

It features internal compensation for unity-gain stability, low input capacitance (2.1pF common-mode), and ESD-protected inputs rated to 4kV. The device is fully specified across –40°C to 125°C and supports both single-supply (2.8V–6V) and split-supply (±5V) operation in its HV variant - though LTC6244HMS8#TRPBF is the standard-voltage, high-temp version.

FAQ

What is the maximum operating temperature rating for LTC6244HMS8#TRPBF?

The LTC6244HMS8#TRPBF is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature limited to 150°C. This H-grade qualification makes it suitable for under-hood automotive, industrial control, and sterilizable medical equipment where thermal robustness is critical. The datasheet guarantees all electrical specifications across this full range.

Does LTC6244HMS8#TRPBF support single-supply operation?

Yes, LTC6244HMS8#TRPBF supports true single-supply operation from 2.8V to 6V. Its input common-mode range extends to the negative rail (V–), and its rail-to-rail output swings within 35mV of both supply rails - enabling full-scale signal handling in 3V and 5V systems without level-shifting circuitry or dual supplies.

What is the typical input bias current of LTC6244HMS8#TRPBF at 125°C?

The typical input bias current of LTC6244HMS8#TRPBF remains 1pA at 25°C and increases to ≤2pA at 125°C, as confirmed in the "LTC6244H" section of the datasheet (page 6, IB parameter). This ultra-low, temperature-stable bias is essential for preserving accuracy in high-impedance photodiode and piezoelectric sensor interfaces across harsh thermal environments.

Can LTC6244HMS8#TRPBF drive capacitive loads directly?

LTC6244HMS8#TRPBF is not unity-gain stable into heavy capacitive loads. The datasheet shows overshoot increases significantly above 100pF (Figure G30–G32). For loads >100pF, a series isolation resistor (e.g., 10Ω–50Ω) between the output and capacitor is required to maintain stability and prevent ringing - especially critical in transimpedance amplifier configurations with photodiode junction capacitance.

Is LTC6244HMS8#TRPBF pin-compatible with other variants in the LTC6244 family?

Yes, LTC6244HMS8#TRPBF is pin-compatible with all MSOP-8 variants in the LTC6244 family (e.g., LTC6244CMS8#TRPBF, LTC6244IMS8#TRPBF, LTC6244HVCMS8#TRPBF), sharing identical pinout, footprint, and solder-reflow profile. Differences lie solely in temperature grade and supply voltage rating - the H-grade part operates up to 125°C on 2.8V–6V, while HV versions support ±5V supplies.
