140V Precision Op Amp Features 3pA Bias Current, 3.5µVP-P
Noise for High Gain Applications
MILPITAS, CA – January 30, 2013 – Linear Technology announces the LTC6090, a precision
operational amplifier that operates on a supply voltage up to 140V (or ±70V). Its combination of
rail-to-rail output, 3pA (typical) input bias current, 1.6mV maximum input offset voltage and
3.5µVP-P low frequency noise delivers the precision required for high performance ATE, piezo
driver, and DAC buffer applications. An enhanced slew rate of 19V/µs allows the output to
swing 140V in less than 8µs. Gain bandwidth product is 10MHz.
The LTC6090 is optimized both for designs with high impedance inputs and those
sensitive to leakage currents. In addition to a standard SO-8 package with exposed pad, the
LTC6090 is available in a TSSOP package with guard pins. This allows a guard ring to be easily
routed around the input to completely enclose it.
Thermal characteristics are a concern for any high voltage space-constrained system. The
LTC6090 is designed with these challenges in mind. Supply current is only 3.9mA max. Output
current is typically ±10mA. 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. Both TSSOP-16 and SOIC-8 package versions include an exposed pad to
minimize thermal resistance.
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. Prices start at $3.45 each in quantities of 1,000. For
