May 2003 FN1924.7 4MHz, BiMOS Microprocessor Operational Amplifier with MOSFET Input/CMOS Output
CA5160 is an integrated circuit operational amplifier that bines the advantage of both CMOS and bipolar transistors on a monolithic chip. The CA5160 is a frequency pensated version of the popular CA5130 series. It is designed and guaranteed to operate in microprocessor or logic systems that use +5V supplies. 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 mon-mode input voltage capability down to 0.5V below the negative supply terminal, an important attribute in single supply applications. A plementary symmetry MOS (CMOS) transistor pair, capable of swinging the output voltage to within 10mV of either supply voltage terminal (at very high values of load impedance), is employed as the output circuit. The CA5160 operates at supply voltages ranging from +5V to +16V, or ±2.5V to ±8V when using split supplies, and have terminals for adjustment of offset voltage for applications requiring offset-null capability. Terminal provisions are also made to permit strobing of the output stage. It has guaranteed specifications for 5V operation over the full military temperature range of -55oC to 125oC.
