CA3260AE

CA3260, CA3260A ® Data Sheet December 10, 2009 4MHz, BiMOS Operational Amplifier with MOSFET Input/CMOS Output CA3260A and CA3260 are integrated circuit operational amplifiers that combine the advantage of both CMOS and bipolar transistors on a monolithic chip. The CA3260 series circuits are dual versions of the popular CA3160 series. Gate protected P-Channel MOSFET (PMOS) transistors are used in the input circuit to provide very high input impedance, very low input current, and exceptional speed performance. The use of PMOS field effect transistors in the input stage results in common mode input voltage capability down to 0.5V below the negative supply terminal, an important attribute in single supply applications.

Applications The CA3260 Series circuits operate at supply voltages ranging from 4V to 16V, or ±2V to ±8V when using split supplies. The CA3260A offers superior input characteristics over those of the CA3260. • Long Duration Timers/Monostables PART MARKING TEMP.
