RC4097

The RC4097 is a micropower device that can be used to improve the performance of a wide range of precision operational amplifier applications. Essentially, a low-power idling current, low IB version of the popular OP-07 industry type, the RC4097 can replace FET-input opamps in circuits requiring low input bias currents while realizing significant improvements in voltage noise, VOS and Vo drift. The other input specifications, such as SMRR and PSRR, support the high level of precision performance, allowing upgrading of many instrumentation, low-level signal conditioning, sample-and-hold, and data conversion applications. The superb performance of the RC4097 is a result of advanced design and processing techniques, including post-package trimming of the input offset voltage, and superbeta proc- essing of the input transistors. Picoampere input bias currents are maintained over the full military temperature range through the use of bias cancellation techniques in the design of the input stage. The RC4097 offers lower VOS drift, lower VOS, higher open-loop gain and better CMRR than industry-standard OP-97 or LT1012 types. The RC4097 is available in 8-lead plastic or ceramic DIPs, TO-99 metal cans, and plastic small outline packages. Military, industrial, and commercial temperature ranges can be selected, and Mil-Std-8838 processing is available.

The features of RC4097 can be summarized as (1)low input offset voltage - 15 v max; (2)low Vos driit - 0.3 V/°C max; (3)low input bias current- +25°C, 100A max; -55°C to 600 pA max; (4)high gain - 1000 V/mV min; (5)high CMRR - 120 dB min; (6)high PSRR 114 dB min; (7)low supply current- 600 A max; (8)low noise 0.5 Vp-p (0.1 to 10 Hz); (9)replaces OP-97, LT1012.

The absolute maximum ratings of RC4077 are (1)supply voltage: ±22V; (2)Input Voltage*: ±22V; (3)differential input voltage: 30V; (4)internal power dissipation**: 500 mW; (5)output short circuit duration: indefinite; (6)storage temperature range: -65°C to +150°C; (7)operating temperature range :RM4097A -55°C to +125°C; RV4097A,E,F (Hermetic) -25°C to +85°C; RC4097A,E,F (Plastic) 0°C to +70°C; (8)lead soldering temperature (SO-8, 10 sec) +260°C, (DIP, LCC, TO-99; 60 sec) +300°C.(*For supply voltages less than :±22V the absolute maximum input voltage is equal to the supply voltage. **Observe package thermal characterics.).
