RC4277EN

The RC4277EN belongs to RC4277 family which provides the highest precision available in a dual bipolar operational amplifier which is available in 8-lead plastic and ceramic DIPs, and can be ordered with Mil-Std-883 Level B processing. A monolithic dual version of the RC4077, the RC4277EN is designed to replace OP-207, LT1002, OP-07 and OP-77 type amplifiers in applications requiring high PC board layout density. The high performance of the RC4277EN results from two innovative and unconventional manufacturlng steps, plus careful circuit layout and design. The RC4277EN has a well-balanced, mutually supporting set of input specifications. Low Vos, low is, high open-loop gain, and excellent matching characteristics combine to raise the performance level of many instrumentation, low-level signal conditioning, and data conversion applications. PSRR, CMRR, Vos drift, and noise levels also support high precision operation. The key steps are SiCr thin-film resistor deposition and post-package trimming of the input offset voltage characteristic. The low ±30V max Vos specification ls maintained ln high-volume production by way of the postpackage trlm procedure, where internal resistors are trimmed through the device input leads at the final test operation. Devices retain this low offset through the stability and accuracy of the trimmed thin-fitm reslstors.

The features of RC4277EN can be summarized as (1)high do precision; (2)very low Vos - 30V max; (3)very low Vos drift - 0.3 V/°C max; (4)high open-loop gain - 5M min; (5)high CMRR - 120 dB min; (6)high PSRR- 110 db min; (7)low noise - 0.35 Vp-p (0.1 to 10 Hz); (8)low bias current- 4.0 nA max; (9)low power consumption - 120 mW max.

The absolute maximum ratings of RC4277EN are (1)supply voltage: ±18V; (2)input voltage: ±18V; (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 RM4277: -55°C to 125°C, RV4277 -25°C to +85°C, RC4277: 0 °C to +70°C; (8)lead soidering temperature (60 sec): +300°C (For supply voltages less than±18V, the absolute maximum input voltage is equal to the supply voltage.
