Analog Devices Inc. LTC6090HS8E#TRPBF

Overview

LTC6090HS8E#TRPBF from Analog Devices (formerly Linear Technology) is a high-voltage, precision CMOS rail-to-rail output operational amplifier with ±70V supply capability, 12MHz gain-bandwidth product, 21V/µs slew rate, and 50pA max input bias current. It features thermal warning (TFLAG), output disable (OD), and operates across –40°C to 125°C for high-reliability piezo drivers and photodiode amplifiers.

For engineers reviewing the LTC6090HS8E#TRPBF datasheet, LTC6090HS8E#TRPBF pinout, LTC6090HS8E#TRPBF application, or LTC6090HS8E#TRPBF equivalent, key selection criteria include guaranteed operation at 125°C junction temperature, ±70V supply tolerance, picoamp-level input bias current over full temperature range, rail-to-rail output swing into 50mA loads, and integrated thermal flag with 145°C activation threshold.

Technical Context

The LTC6090HS8E#TRPBF uses a proprietary high-voltage CMOS process enabling rail-to-rail output swing while maintaining low offset drift (±5µV/°C max) and 0.1Hz–10Hz noise of 3.5µV_P-P. Its unity-gain stable architecture supports high-impedance buffering without external compensation.

It integrates a die temperature sensor feeding an open-drain TFLAG output and an active-low OD pin that disables only the output stage-preserving input bias and reference circuitry-enabling fast wake-up and safe thermal shutdown coordination when tied together.

FAQ

What is the maximum junction temperature rating for the LTC6090HS8E#TRPBF?

The LTC6090HS8E#TRPBF is rated for operation up to 125°C junction temperature, with thermal shutdown activating at 175°C and thermal warning (TFLAG) asserting at 145°C. Its H-grade qualification guarantees full electrical performance across –40°C to 125°C ambient, supported by the exposed-pad SOIC package's 5°C/W junction-to-case thermal resistance.

Does the LTC6090HS8E#TRPBF support single-supply operation?

Yes, the LTC6090HS8E#TRPBF supports single-supply operation up to 140V total supply (e.g., V+ = 140V, V– = 0V). Its input common-mode range extends from V– +3V to V+ –3V, and its rail-to-rail output can swing within 10mV of either rail under light load-enabling true single-supply use in high-voltage sensor interfaces and programmable supplies.

How does the OD pin function on the LTC6090HS8E#TRPBF?

The OD pin on the LTC6090HS8E#TRPBF is an active-low output disable control referenced to the COM pin. When pulled ≤0.65V below COM, it disables only the output stage-leaving input bias and reference circuits active-reducing supply current to ~580µA while enabling sub-microsecond wake-up. An internal 2MΩ pull-up holds OD high by default if left floating.

Can the LTC6090HS8E#TRPBF drive capacitive loads?

Yes, the LTC6090HS8E#TRPBF is specified to drive up to 200pF of capacitive load while maintaining stability, per the datasheet's small-signal frequency response curves and phase margin (≥60°) testing at CL = 50pF. For larger loads, external isolation resistors or feedback compensation may be required to preserve stability and settling performance.

What is the purpose of the COM pin on the LTC6090HS8E#TRPBF?

The COM pin on the LTC6090HS8E#TRPBF serves as a dedicated reference node for the OD and TFLAG pins, enabling safe interfacing with low-voltage logic (e.g., microcontrollers) without level shifters. It must be tied to the low-voltage ground or left floating (where it rises to ~30% above mid-supply); voltage between COM and OD or TFLAG must remain within –3V to +7V to avoid damage.
