News Release www.linear.com Precision Op Amps Operate on 140V Supply MILPITAS, CA – August 4, 2014 – Linear Technology announces the LTC6091 and LTC6090-5, additions to the LTC6090 family of precision operational amplifiers which operate on a supply voltage up to 140V (±70V). The dual LTC6091 features separate output disable pins, making it useful in high voltage multiplexed applications. The decompensated single LTC6090-5 amplifier offers higher speed and is stable at a gain of 5 or above. The LTC6090, LTC6090-5, and LTC6091 combine wide supply range, high precision, and low noise. Input offset voltage is 1.25mV max over temperature, and low frequency (1/f) noise is 3.5μVP-P from 0.1Hz to 10Hz. The CMOS input structure keeps the input bias current to 50pA maximum at 85°C, making the LTC6090 family suitable for sensor circuits and other applications requiring high input impedance. The decompensated LTC6090-5 offers 24MHz gain-bandwidth product and 37V/µs slew rate, compared with 12MHz and 21V/µs for the gain-of-1 stable LTC6090 and LTC6091. Supply current is 3.9mA per amplifier max. Output short-circuit current is typically ±90mA. A thermal flag pin (TFLAG) signals when the device junction temperature exceeds 145°C. This pin can be connected to the Output Disable pin for active thermal management. The LTC6090 and LTC6090-1 are available in 8-pin SOIC and 16-pin TSSOP packages. The LTC6091 is offered in a 16-pin 4mm x 6mm QFN package. Each of these packages includes an exposed pad to minimize thermal resistance. Prices start at $3.45 each for the LTC6090 and LTC6090-5, and $6.61 each for the LTC6091 in quantities of 1,000.
