| Order this document by MC1776C/D MC1776C Micropower Programmable Operational Amplifier This extremely versatile operational amplifier features low power consumption and high input impedance. In addition, the quiescent currents within the device may be programmed by the choice of an external resistor value or current source applied to the Iset input. This allows the amplifier's characteristics to be optimized for input current and power consumption despite wide variations in operating power supply voltages. * 1.2 V to 18 V Operation PROGRAMMABLE OPERATIONAL AMPLIFIER SEMICONDUCTOR TECHNICAL DATA * * * * * Wide Programming Range Offset Null Capability No Frequency Compensation Required Low Input Bias Currents Short Circuit Protection 8 1 Resistive Programming (See Figure 1) P1 SUFFIX PLASTIC PACKAGE CASE 626 Rset to Ground 7 VCC - + 4 VEE 8 Rset Iset = 6 3 Rset to Negative Supply (Recommended for supply voltage less than 6.0 V) 8 1 2 3 2 7 VCC - + 4 8 Rset VEE Iset = VCC - 0.6 - VEE Rset Iset = 15 A 160 k 360 k 750 k 2.0 M 6 D SUFFIX PLASTIC PACKAGE CASE 751 (SO-8) VCC - 0.6 Rset Typical Rset Values VCC, VEE 6.0 V 10 V 12 V 15 V Iset = 1.5 A 3.6 M 6.2 M 7.5 M 10 M Iset = 15 A 360 k 620 k 750 k 1.0 M 1.5 V 3.0 V 6.0 V 15 V Typical Rset Values VCC, VEE Iset = 1.5 A 1.6 M 3.6 M 7.5 M 20 M PIN CONNECTIONS Offset Null Input Invert Noninvert VEE 1 2 3 4 8 - + 7 6 5 Iset VCC Output Offset Null Active Programming FET Current Source 7 - + 8 VG VEE Pins not shown are not connected.
