Analog Devices Inc. LTC6087HMS8#PBF

Overview

LTC6087HMS8#PBF from Analog Devices (formerly Linear Technology) is a dual, rail-to-rail input/output, low-noise CMOS operational amplifier optimized for high-impedance sensor signal conditioning. It delivers 14MHz gain bandwidth, 7.2V/µs slew rate, 12nV/√Hz input voltage noise at 1kHz, 750µV max offset voltage, and 1pA typical input bias current at 25°C - enabling precision amplification in portable medical sensors and shock/vibration transducers operating from 2.7V to 5.5V supplies.

For engineers reviewing the LTC6087HMS8#PBF datasheet, LTC6087HMS8#PBF pinout, LTC6087HMS8#PBF application, or LTC6087HMS8#PBF equivalent, this page provides verified package mapping (8-lead MSOP), temperature-rated performance (–40°C to 125°C), shutdown functionality (2.3µA per amp), rail-to-rail output swing (within 30mV of rails), and confirmed alternative options for low-bias, low-noise dual op-amp selection.

Technical Context

The LTC6087HMS8#PBF employs complementary PMOS/NMOS input pairs to achieve rail-to-rail common-mode input range (V– to V+), with seamless transition between transistor types near 0.9V–1.3V below V+. Its class AB output stage supports ±45mA short-circuit current while maintaining 30mV rail headroom under no-load conditions.

Internal ESD protection diodes define the 1pA input bias current baseline, which rises to 15pA at 85°C and remains stable across supply voltages (2.7V–5.5V). The device features unity-gain stability, 47° phase margin, and 0.8µs 0.1% settling time - validated for use in single-supply transducer interfaces with capacitive loads up to 100pF.

FAQ

What is the maximum operating temperature range for the LTC6087HMS8#PBF?

The LTC6087HMS8#PBF is rated for continuous operation from –40°C to 125°C, with all electrical specifications guaranteed across this full industrial-plus-automotive temperature range. This H-grade qualification distinguishes it from the C-grade (–40°C to 85°C) variant and ensures reliability in engine bay, motor drive, and downhole sensing applications where ambient temperatures exceed 105°C.

Does the LTC6087HMS8#PBF include shutdown functionality?

No, the LTC6087HMS8#PBF in the 8-lead MSOP package does not include shutdown pins. Shutdown capability (SHDNA/SHDNB) is exclusive to the 10-lead DFN (LTC6087HDD#PBF) variant. The MS8 package provides dual op-amp functionality only - all specifications for supply current (1.05mA/amp) and noise apply to active operation without power-down control.

What is the input common-mode voltage range of the LTC6087HMS8#PBF?

The LTC6087HMS8#PBF features true rail-to-rail input operation, with common-mode voltage range specified from V– to V+ across the full supply range (2.7V to 5.5V) and temperature range (–40°C to 125°C). This allows direct interfacing with sensors whose output spans the entire supply rail, eliminating level-shifting circuitry in single-supply systems.

How does the LTC6087HMS8#PBF achieve its 1pA input bias current specification?

The LTC6087HMS8#PBF achieves 1pA typical input bias current through CMOS input transistors with optimized gate oxide and layout, combined with on-chip ESD protection diodes whose leakage defines the bias baseline. This performance is maintained across temperature (15pA at 85°C) and supply voltage, but requires clean PCB layout - including guard rings - to prevent board-level leakage from overwhelming the intrinsic device bias.

Can the LTC6087HMS8#PBF drive capacitive loads, and if so, up to what value?

Yes, the LTC6087HMS8#PBF can drive capacitive loads up to 100pF in unity-gain configuration while maintaining stability. Performance improves in higher-gain configurations, and adding a small series resistor (e.g., 10Ω–50Ω) between output and load further increases capacitive drive capability - essential for driving ADC input filters or long PCB traces without peaking or oscillation.
