Analog Devices Inc. LTC2054HVMPS5#TRMPBF

Overview

LTC2054HVMPS5#TRMPBF from Analog Devices (formerly Linear Technology) is a single-channel, micropower, zero-drift operational amplifier in a 5-lead TSOT-23 package, rated for operation from –55°C to 150°C. It delivers 3 μV max input offset voltage, 30 nV/°C max drift, 1.6 μV_P-P (0.01 Hz–10 Hz) noise, rail-to-rail output swing, and 500 kHz gain-bandwidth product. It is designed for precision current sensing in high-reliability industrial and automotive systems.

For engineers reviewing the LTC2054HVMPS5#TRMPBF datasheet, LTC2054HVMPS5#TRMPBF pinout, LTC2054HVMPS5#TRMPBF application, or LTC2054HVMPS5#TRMPBF equivalent, key selection criteria include extended temperature performance (–55°C to 150°C), ultra-low DC error budget, HV supply capability (±5.5 V), and compatibility with low-side current sense topologies requiring sub-10 μV offset stability over temperature.

Technical Context

The LTC2054HVMPS5#TRMPBF employs auto-zeroing architecture with a 1 kHz internal sampling clock to continuously correct input offset and 1/f noise. Its input stage supports common-mode voltage from V– to V+ – 0.9 V under ±5 V supplies and features 130 dB typical PSRR and CMRR.

It operates from a total supply voltage of up to 12 V (±5.5 V), draws only 175–220 μA supply current, and maintains rail-to-rail output swing into 5 kΩ loads - enabling direct interfacing with SAR ADCs and low-voltage microcontrollers without level-shifting.

FAQ

What is the maximum operating temperature range for the LTC2054HVMPS5#TRMPBF?

The LTC2054HVMPS5#TRMPBF is fully specified and guaranteed over –55°C to +150°C. This extended temperature rating is validated per the LTC2054MP/HVMP family specifications and applies across all electrical parameters including input offset voltage, drift, PSRR, and output swing - making it suitable for under-hood automotive, downhole oil/gas, and aerospace applications where thermal stress exceeds standard industrial limits.

Does the LTC2054HVMPS5#TRMPBF support dual-supply operation?

Yes, the LTC2054HVMPS5#TRMPBF supports true dual-supply operation up to ±5.5 V (11 V total). Its absolute maximum rating allows ±5.5 V, and electrical characteristics tables explicitly list performance at ±5 V. The input common-mode range extends to V– to V+ – 0.9 V, and rail-to-rail output swing is maintained under dual-supply conditions - enabling use in traditional bipolar instrumentation circuits without level-shifting.

What is the typical input bias current of the LTC2054HVMPS5#TRMPBF at 25°C?

The typical input bias current of the LTC2054HVMPS5#TRMPBF is ±3 pA at 25°C, with a maximum of ±12 pA over the full –55°C to 150°C range. This ultra-low bias current results from its auto-zeroing architecture and guarded input design, enabling high-impedance sensor interfaces such as thermocouples, pH electrodes, and piezoresistive bridges without significant error from leakage paths.

How does the LTC2054HVMPS5#TRMPBF handle clock feedthrough from its auto-zeroing circuitry?

The LTC2054HVMPS5#TRMPBF exhibits two forms of clock feedthrough due to its 1 kHz auto-zeroing clock: an input-referred residue (<0.2 μV_RMS) and a charge-injection–induced component dependent on source impedance. At source resistances <10 kΩ, the latter is suppressed below the former. Adding a capacitor across the feedback resistor reduces both components by limiting closed-loop bandwidth - a standard practice confirmed in the device's Applications Information section.

Is the LTC2054HVMPS5#TRMPBF pin-compatible with other variants in the LTC2054 family?

Yes, the LTC2054HVMPS5#TRMPBF uses the standard 5-lead TSOT-23 (S5) package and shares identical pinout with all other LTC2054 variants in that package - including LTC2054IS5#TRPBF, LTC2054HS5#TRPBF, and LTC2054HVCS5#TRPBF. Pin 1 is OUT, Pin 2 is V–, Pin 3 is +IN, Pin 4 is –IN, and Pin 5 is V+. This allows drop-in replacement within the same temperature and supply-voltage grade, provided system-level thermal and electrical margins are verified.
