Jun 6, 2017 19MHz 40V Quad Rail-to-Rail Input-Output, Low-Power Operational Amplifiers The ISL71444M features four radiation tolerant, low-power amplifiers optimized to provide maximum dynamic range.
These op amps feature a unique combination of rail-to-rail operation on the input and output as well as a slew
enhanced front-end that provides ultra fast slew rates positively proportional to a given step size. They also offer lowpower, low-offset voltage, and low temperature drift, making it ideal for applications requiring both high DC accuracy
and AC performance. Features Unity gain stable with wide gain-bandwidth product: 19MHz Wide single and dual supply range: 2.7V to 40V max Low input offset voltage: 400ВµV Low current consumption (per amplifier): 1.1mA, typ High large signal slew rate: 60V/Вµs Operating temperature range: -55В°C to +125В°C 14 Ld TSSOP with NiPdAu lead finish Characterized radiation level Low Dose Rate (V+ or V+ 110dB with a В±18V supply. The minimum CMRR performance across the
-55В°C to +125В°C temperature range and radiation is >70dB over the full common-mode input range for power
supply voltages from В±2.5V (5V) to В±18V (36V). 4.3 Input Performance The slew enhanced front-end is a block that is placed in parallel with the main input stage and functions based on the
input differential. 4.4 Input ESD Diode Protection The input terminals (IN+ and IN-) have internal ESD protection diodes to the positive and negative supply rails,
series-connected 600О© current limiting resistors, and an anti-parallel diode pair across the inputs.
