140-V op amp offers precision performance

Paul Buckley -February 04, 2013

The LTC6090's combination of rail-to-rail output, 3 pA (typical) input bias current, 1.6 mV 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 19 V/µs allows the output to swing 140 V in less than 8 µs. Gain bandwidth product is 10 MHz.

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 3.9 mA max. Output current is typically ±10 mA. 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.

Availability and Pricing
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.
