CA5260, CA5260A 3MHz, BiMOS Microprocessor Operational Amplifiers with MOSFET Input/CMOS Output November 1996 Features Description • MOSFET Input Stage provides - Very High ZI = 1.5TΩ (1.5 x 1012Ω) (Typ) - Very Low II = 5pA (Typ) at 15V Operation = 2pA (Typ) at 5V Operation The CA5260A and CA5260 are integrated-circuit operational amplifiers that combine the advantage of both CMOS and bipolar transistors on a monolithic chip. The CA5260 series circuits are dual versions of the popular CA5160 series. They are designed and guaranteed to operate in microprocessor or logic systems that use +5V supplies. • Ideal for Single Supply Applications • Common Mode Input Voltage Range Includes Negative Supply Rail; Input Terminals Can be Swung 0.5V Below Negative Supply Rail • CMOS Output Stage Permits Signal Swing to Either (or Both) Supply Rails • CA5260A, CA5260 Have Full Military Temperature Range Guaranteed Specifications for V+ = 5V • CA5260A, CA5260 are Guaranteed to Operate Down to 4.5V for AOL • Fully Guaranteed to Operate from -55oC to 125oC at V+ = 5V, V- = GND 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. A complementary-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 CA5260 Series circuits operate at supply voltages ranging from 4.5V to 16V, or ±2.25V to ±8V when using split supplies. Applications • Fast Sample-Hold Amplifiers The CA5260, CA5260A have guaranteed specifications for 5V operation over the full military temperature range of -55oC to 125oC. • Long Duration Timers/Monostables Ordering Information • Ground Referenced Single Supply Amplifiers • Ideal Interface with Digital CMOS PART NUMBER (BRAND) • High Input Impedance Wideband Amplifiers • Voltage Followers (e.g., Follower for Single Supply D/A Converter) TEMP.
