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.

The LTC6090 is available in three temperature range grades: 0°C to 70°C, –40°C to 85°C
and –40°C to 125°C junction temperature. The LTC6091 is available in –40°C to 85°C and
–40°C to 125°C junction temperature grades. For more information, visit
