1437 1537 Dual High-Gain Operational Amplifiers GENERAL DESCRIPTION DESIGN FEATURES The RC1437 and RM1537, previously referred to as the 4709, @ Gain and Phase Matching Between Amplifiers integrated circuits are monolithic dual high gain operational @ Low Temperature Drift +3 pV/OC amplifiers. The device is composed of two 709 operational am- @ Large Output Voltage Swing +14 V Typical plifiers. fabricated on a single silicon chip. It has all the out- standing features of the 709. Due to the inherent matching and tracking of parameters, the 1537/1437 has several unique applications: differential in/out amplifiers, non-inverting amplifiers, gain and phase matched channels. The RM1537 operates over a temperature range of ~559C to +1250C, RC 1437 is the commercial temperature range device for operation from OOC to +759C.
