FEATURES
Two-Chip Design High Slew Rate Offset/Drift Voltage Gate Leakage: Noise High CMRR:
BENEFITS
Minimum Parasitics Ensuring Maximum High-Frequency Performance Improved Speed, Settling Time Accuracy Minimum Input Error/Trimming Requirement Insignificant Signal Loss/Error Voltage High System Sensitivity Minimum Error with Large Input Signal
APPLICATIONS
Wideband Differential Amps High-Speed, Temp-Compensated, Single-Ended Input Amps High Speed Comparators Impedance Converters
DESCRIPTION
2N5911/5912 matched pairs JFETs mounted TO-78 package. This two-chip design reduces parasitics gives better performance high frequencies while ensuring extremely tight matching. hermetically-sealed TO-78 package available with full military screening MIL-S-19500 (see Military Information). similar products SO-8 packaged SST440/SST441, TO-71 packaged U440/U441, low-noise SST/U401 series, low-leakage U421/423 data sheets.
