Analog Devices Inc. LTC2050HVHS6#TRMPBF

Overview

LTC2050HVHS6#TRMPBF from Analog Devices is a zero-drift operational amplifier in a 6-lead SOT-23 package, designed for precision DC-coupled signal conditioning. It delivers 0.5µV typical input offset voltage, 10nV/°C offset drift, 1.5µV_P-P (0.01Hz–10Hz) input-referred noise, and rail-to-rail output swing into 2kΩ loads-enabling high-accuracy thermocouple amplification and strain gauge interfaces.

For engineers reviewing the LTC2050HVHS6#TRMPBF datasheet, LTC2050HVHS6#TRMPBF pinout, LTC2050HVHS6#TRMPBF application, or LTC2050HVHS6#TRMPBF equivalent, key selection criteria include its ±5.5V dual-supply operation, –40°C to 125°C temperature grade, active-low shutdown capability (3µA quiescent), and guaranteed 3µV max offset over temperature-critical for automotive sensor front-ends and industrial data acquisition systems.

Technical Context

The LTC2050HVHS6#TRMPBF uses auto-zeroing architecture with a 7.5kHz internal sampling clock to eliminate DC offset and drift across supply, temperature, and common-mode voltage variations. Its input stage supports common-mode range from V– to (V+ – 1.3V), and PSRR/CMRR exceed 130dB at DC, ensuring immunity to supply and interference coupling in noisy environments.

It features an enhanced output stage capable of driving 2kΩ loads to both rails, open-loop gain of 140dB, 3MHz gain-bandwidth product, and 2V/µs slew rate-supporting stable closed-loop configurations up to unity gain while maintaining sub-microvolt DC accuracy in low-frequency instrumentation circuits.

FAQ

What is the maximum input common-mode voltage range for LTC2050HVHS6#TRMPBF?

The LTC2050HVHS6#TRMPBF supports an input common-mode voltage range from V– to (V+ – 1.3V). With ±5.5V supplies, this translates to –5.5V to +4.2V, enabling direct interfacing with sensors whose outputs swing near the negative rail-such as low-side current shunts-without level-shifting circuitry. This specification is guaranteed over the full –40°C to 125°C operating range.

Does LTC2050HVHS6#TRMPBF require external capacitors for stability in unity-gain configurations?

No, LTC2050HVHS6#TRMPBF is internally compensated and remains stable at unity gain without external compensation components. Its 3MHz gain-bandwidth product and 2V/µs slew rate ensure robust step response with <1% overshoot into 10kΩ loads. However, for driving capacitive loads >100pF, a small series resistor (≤50Ω) at the output is recommended to maintain phase margin.

How does the shutdown feature of LTC2050HVHS6#TRMPBF affect input/output states?

When the SHDN pin of LTC2050HVHS6#TRMPBF is pulled low, the device enters shutdown mode: supply current drops to ≤3µA, internal clocking halts, and both inputs and output enter high-impedance states. This prevents loading of upstream sensors or downstream ADCs during sleep cycles. The output does not clamp or short-it floats, preserving signal integrity in multi-amplifier systems.

Is LTC2050HVHS6#TRMPBF suitable for measuring µV-level signals from RTDs or thermistors?

Yes, LTC2050HVHS6#TRMPBF is well-suited for µV-level RTD/thermistor measurements due to its 0.5µV typical input offset, 10nV/°C drift, and 1.5µV_P-P (0.01Hz–10Hz) noise. When configured as a low-gain difference amplifier with 0.1% resistors, it achieves <0.1°C resolution in 3-wire RTD bridges-provided layout minimizes thermoelectric EMFs and EMI pickup at the input traces.

What packaging and marking identify the LTC2050HVHS6#TRMPBF variant?

LTC2050HVHS6#TRMPBF is supplied in a 6-lead Plastic TSOT-23 (S6) package with lead-free finish, tape-and-reel packaging (500 units/reel), and part marking "LTAEK". The "H" suffix denotes the –40°C to 125°C temperature grade, "HV" indicates high-voltage operation (±5.5V), and "S6" specifies the 6-lead SOT-23 footprint-distinguishing it from 5-lead (S5) or SO-8 (S8) variants.
