RC4277

The RC4277 has the following features including High DC precision;Very low VOS-30V;Very low VOS drift-0.3V/;High open-loop gain -5000 V/mV;High CMRR -120 dB.

The RC4277 provides the highest precision available in a dual bipolar operational amplifier. A monolithic dual version of the RC4077, the RC4277 is designed to replace OP-07 and OP-77 type amplifiers in applications requiring high PC board layout density. The RC4277 has a well-balanced,mutually supporting sct of input spccifications. Low VOS,low IR, high open-loop gain, and excellent mulching 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 high performance of the RC4277 results from two innovative and unconventional manufacturing steps, plus careful circuit layout and design. The key steps are SiCr thin-film resistor deposition and post-package trimming of the input offset voltage characteristic. The low 75 V max VpS specification is maintained in high-volume production by way of the post-package trim procedure, where internal resistors are trimmed through the device input leads at the final tcst opcration. Dcviccs rctain this low offsct through the stability and accuracy of the trimmed thin-film resistors. The RC4277 is available in 8-lead plastic and ceramic DIPS.

Life support devices or systems are devices or systems which, (a) are intended for surgical implant into the body,or (b) support or sustain life, and (c) whose failure to perform when properly used in accordance with instructions for use provided in the labeling, can be reasonably expected to result in a significant injury of the user.A critical component in any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system, or to affect RC4277's safety or effectiveness.
