| RH1814M Quad 3mA, 100MHz, 750V/s Operational Amplifier U WW W U 50k 5.5V RH1814M -5.5V RH1814M BI DESCRIPTIO ABSOLUTE (Note 1) AXI U RATI GS The RH1814 is a quad, low power, high speed, very high slew rate operational amplifier with excellent DC performance, reduced supply current, lower input offset voltage, lower input bias current and higher DC gain than other devices with comparable bandwidth. The circuit topology is a voltage feedback amplifier with the slewing characteristics of a current feedback amplifier. The output drives a 100 load to 3.35V with 5V supplies. On a single 5V supply, the output swings from 1.1V to 3.7V with a 100 load connected to 2.5V. The amplifiers are stable with a 1000pF capacitive load making them useful in buffer and cable driver applications. The RH1814 is manufactured on Linear Technology's advanced low voltage complementary bipolar process.

Note 2: Differential inputs of 6V are appropriate for transient operation only, such as during slewing. Large sustained differential inputs can cause excessive power dissipation and may damage the part. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift. Note 5: This parameter is not 100% tested. 5 RH1814M TABLE 2: ELECTRICAL TEST REQUIRE E TS MIL-STD-883 TEST REQUIREMENTS Final Electrical Test Requirements (Method 5004) Group A Test Requirements (Method 5005) Group B and D for Class S End Point Electrical Parameters (Method 5005) * PDA applies to subgroup 1. See PDA Test Notes. SUBGROUP 1*,2,3,4,5,6 1,2,3,4,5,6 1,2,3 PDA Test Notes The PDA is specified as 5% based on failures from group A, subgroup 1, tests after cooldown as the final electrical test in accordance with method 5004 of MIL-STD-883. The verified failures of group A, subgroup 1, after burn-in divided by the total number of devices submitted for burn-in in that lot shall be used to determine the percent for the lot.
