Product details
Overview
LTC2064HMS8#PBF from Analog Devices is a dual, zero-drift, micropower operational amplifier in an 8-lead MSOP package, specified for –40°C to 125°C operation. It delivers 2 µA maximum supply current per amplifier, 5 µV max input offset voltage, and 0.02 µV/°C max offset drift - enabling high-resolution sensor signal conditioning in ultra-low-power battery or energy-harvesting systems.
For engineers reviewing the LTC2064HMS8#PBF datasheet, LTC2064HMS8#PBF pinout, LTC2064HMS8#PBF application, or LTC2064HMS8#PBF equivalent, key selection criteria include rail-to-rail I/O, integrated EMI filtering (114 dB at 1.8 GHz), shutdown current ≤170 nA, and guaranteed performance over extended temperature range - critical for portable instrumentation and gas detection designs.
Technical Context
The LTC2064HMS8#PBF employs auto-zeroing and chopper-stabilized architecture with 5 kHz internal chopping frequency, achieving near-zero DC errors while maintaining 20 kHz gain-bandwidth product and 3.5 V/ms slew rate. Its self-calibrating circuitry continuously corrects input offset and drift without introducing idle tones.
Rail-to-rail input and output stages operate from 1.7 V to 5.25 V supply, with CMRR ≥108 dB and PSRR ≥106 dB across full temperature range. Integrated EMI filter rejects RF interference up to 2.4 GHz, and low-charge power-up minimizes transient disturbance during duty-cycled enable events.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8628ARZ | Single-channel, 1 µA supply current, 1 µV max offset, but no shutdown pin or EMI filter | Lacks dual-channel integration and RF immunity - requires external shutdown control and shielding | Preferred when single-channel operation and lowest possible offset dominate over power cycling and EMI robustness |

FAQ
What is the maximum operating temperature range for the LTC2064HMS8#PBF?
The LTC2064HMS8#PBF is fully specified from –40°C to +125°C, with all key parameters - including input offset voltage, offset drift, supply current, and shutdown current - guaranteed across this extended industrial temperature range. This makes the LTC2064HMS8#PBF suitable for under-hood automotive sensors, industrial process controllers, and outdoor environmental monitoring where ambient temperatures exceed standard commercial limits.
Does the LTC2064HMS8#PBF support rail-to-rail input and output operation?
Yes, the LTC2064HMS8#PBF supports true rail-to-rail input and output operation across its full 1.7 V to 5.25 V supply range. Input common-mode voltage extends from (V–) – 0.1 V to (V+) + 0.1 V, and output swing reaches within 0.1 mV of each rail under light loads. This capability allows the LTC2064HMS8#PBF to maximize dynamic range in low-voltage systems such as single-cell battery-powered devices.
How does the EMI rejection feature of the LTC2064HMS8#PBF improve system reliability?
The LTC2064HMS8#PBF integrates an on-chip EMI filter delivering 114 dB rejection at 1.8 GHz - effectively suppressing interference from cellular, WiFi, and Bluetooth transceivers. This eliminates the need for external RC filters or shielded enclosures in portable medical and industrial IoT devices, reducing bill-of-materials cost and PCB area while ensuring consistent measurement accuracy in electromagnetically congested environments.
Can the LTC2064HMS8#PBF be used in single-supply configurations?
Yes, the LTC2064HMS8#PBF operates reliably in single-supply configurations from 1.7 V to 5.25 V. Its rail-to-rail input stage accepts common-mode voltages down to V– and up to V+, and its output swings to within millivolts of both rails. This enables direct interfacing with microcontroller ADCs and reference buffers without level-shifting circuitry - simplifying design in coin-cell or energy-harvesting powered systems.
What is the typical power-up time for the LTC2064HMS8#PBF after asserting the SHDN pin?
The typical power-up time for the LTC2064HMS8#PBF is 2 ms after the SHDN pin transitions from logic low (V–) to logic high (≥1.8 V). During this interval, the internal self-calibration circuit stabilizes, and output settles to final value with minimal overshoot due to low-charge power-up design. This fast wake-up supports high-duty-cycle sampling in time-sensitive applications like real-time gas concentration analysis.
