RC4077

The RC4077 is an advanced, ultra-high performance precision bipolar operational amplifier. its high precision performance results from two innovative and unconventional manufacturin steps, plus careful circuit layout and design. Thin-film resistor technology and a novel method of digital offset nulling are the key steps. A low :10 l.l.V offset voltage is delivered via a patented, proprietary Vos nulling adjustment. Devices retain this low offset through the stability and accuracy of Si-Or thin-film resistors.For applications needing the lowest input offset voltage drift with temperature (TO Vos), the grade has a worst-case specification of just 0.1 pv/°C. Designed to upgrade OP-07 and other low-Is bipolar precision types, the RC4077 has a well-balanced, mutually supporting set of input specifications. Low Vas, low Is, and high openloop gain combine to raise the performance level of many instrumentation, low-level signal conditioning, and data conversion applications. PSRR, CMRR, drift, and noise levels also support high precision operation. The RC4077 is available in LCC, SO-8 (small outline), TO-99 can, plastic mini-DIP and ceramic mini-DIP packages, and can be ordered with Mil-Std-883 Level processing.

The features of RC4077 can be summarized as (1)ultra-low Vos- 10 V max; (2)ultra low Vos drift - 0.1 V/°C max (B grade only); (3)outstanding gain linearity; (4)high gain - 5000 V/mV min; (5)high CMRR - 120 dB min; (6)high PSRR -110 dB min; (7)low noise - 0.3 Vp-p (0.1 to 10 Hz); (8)low input bias current- 2.0 nA max; (9)low power consumption - 50 mW max; (10)replaces OP-07, OP-77, 725, 108, 741 types.

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 :RM4077A -55°C to +125°C; RV4077A,E,F (Hermetic) -25°C to +85°C; RC4077A,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.)
