The LT1457 is a dual, JFET input op amp optimized for handling large capacitive loads in combination with precision performance.
Precision specifications include 220µV offset voltage in plastic and surface mount packages. At 70°C input bias current is 50pA, input offset current is 20pA. Channel separation is 130dB.
Other dual JFET input op amps from ADI include the LT1057, which is three times faster than the LT1457 but at the expense of significantly lower capacitive load handling capability; and the LT1113 with 4.5nV/rt Hz voltage noise.
Applications
- Sample-and-Hold (Drives Large Hold Capacitors)
- A/D and D/A Converters
- Photodiode Amplifiers
- Voltage-to-Frequency Converters
