Analog Devices Inc. LTC2057IMS8#TRPBF

Overview

LTC2057IMS8#TRPBF from Analog Devices (formerly Linear Technology) is a high-voltage, low-noise, zero-drift operational amplifier in an 8-lead MSOP package, delivering 4μV max input offset voltage, 0.015μV/°C max drift, and 200nV_P-P DC–10Hz input noise. It operates from ±2.375V to ±18V supplies (4.75V–36V total), features rail-to-rail output, and is used in precision thermocouple amplifiers and high-resolution data acquisition systems.

For engineers reviewing the LTC2057IMS8#TRPBF datasheet, LTC2057IMS8#TRPBF pinout, LTC2057IMS8#TRPBF application, or LTC2057IMS8#TRPBF equivalent, key selection criteria include its guaranteed 4μV max V_OS over –40°C to 85°C, shutdown mode with 3μA typical quiescent current, and input common-mode range extending to V– – 0.1V - critical for low-side current sensing and reference buffering.

Technical Context

The LTC2057IMS8#TRPBF employs auto-zeroing and chopper stabilization to suppress 1/f noise and offset drift, achieving sub-microvolt DC precision without external trimming. Its internal 100kHz chopping frequency is actively suppressed to minimize ripple artifacts at the output.

It integrates a dedicated shutdown control architecture with SD and SDCOM pins, enabling precise enable/disable sequencing independent of supply rails. The input stage supports common-mode voltages down to V– – 0.1V, and the output delivers rail-to-rail swing with <100mV saturation under 5mA load - essential for single-supply instrumentation interfaces.

FAQ

What is the maximum input offset voltage specification for LTC2057IMS8#TRPBF over its full operating temperature range?

The LTC2057IMS8#TRPBF has a maximum input offset voltage of 4μV across the full –40°C to +85°C operating temperature range, as specified in the Absolute Maximum Ratings table of the official datasheet. This value is guaranteed by design and applies to all units shipped in the I-grade temperature version, making it suitable for applications requiring consistent DC accuracy without post-manufacturing calibration.

Does LTC2057IMS8#TRPBF support rail-to-rail input common-mode voltage?

No, the LTC2057IMS8#TRPBF does not support rail-to-rail input common-mode voltage. Its specified input common-mode range is V– – 0.1V to V+ – 1.5V. While this extends below the negative rail (enabling true low-side current sensing), it does not reach the positive rail - limiting use in certain single-supply configurations where inputs approach V+.

What is the shutdown current consumption of LTC2057IMS8#TRPBF at 25°C?

At 25°C, the LTC2057IMS8#TRPBF draws 3μA typical supply current in shutdown mode, as confirmed in the Electrical Characteristics table (page 4 of the datasheet). This value increases to 9μA maximum at +125°C, ensuring ultra-low power state retention in battery-backed or energy-conscious instrumentation designs.

Can LTC2057IMS8#TRPBF drive a 10kΩ load while maintaining rail-to-rail output swing?

Yes, the LTC2057IMS8#TRPBF maintains rail-to-rail output swing into a 10kΩ load. Per the Electrical Characteristics table, output voltage swing is specified with RL = 10kΩ, and typical high-side swing is within 15mV of V+ and low-side swing within 12mV of V– at 25°C - meeting rail-to-rail definition for high-impedance interfacing with precision ADCs and filters.

Is the MS8 package of LTC2057IMS8#TRPBF lead-free and RoHS compliant?

Yes, the LTC2057IMS8#TRPBF is manufactured with lead-free finish and complies with RoHS Directive 2011/65/EU. The "#TRPBF" suffix explicitly denotes tape-and-reel packaging with lead-free (Pb-free) termination, and the part marking "LTFGK" confirms compliance per Analog Devices' lead-free part marking standards.
