AD8469
AD8469 is Single-Supply TTL/CMOS Comparator manufactured by Analog Devices.
Data Sheet Fast, Rail-to-Rail, Low Power, 2.5 V to 5.5 V, Single-Supply TTL/CMOS parator AD8469 Features Qualified for automotive applications Fully specified rail-to-rail at VCC = 2.5 V to 5.5 V Input mon-mode voltage: VEE - 0.2 V to VCC + 0.2 V Low glitch TTL-/CMOS-patible output stage 40 ns propagation delay Low power: 1.4 m W at 2.5 V Shutdown pin Programmable hysteresis Power supply rejection better than - 50 d B - 40°C to +125°C operation APPLICATIONS High speed instrumentation Clock and data signal restoration Logic level shifting or translation High speed line receivers Threshold detection Peak and zero-crossing detectors High speed trigger circuitry Pulse-width modulators Current/voltage controlled oscillators GENERAL DESCRIPTION The AD8469 is a fast parator fabricated on XFCB2, an Analog Devices, Inc., proprietary process. This parator is exceptionally versatile and easy to use. Features include an input range from VEE - 0.2 V to VCC + 0.2 V, low noise, TTL- and CMOS-patible output drivers, adjustable hysteresis control, and a shutdown input. The device offers a 40 ns propagation delay driving a 15 p F load with 10 m V overdrive on 500 µA typical supply current. A flexible power supply scheme allows the device to operate from a single +2.5 V positive supply with a - 0.2 V to +2.7 V input signal range up to a +5.5 V positive supply with a - 0.2 V to +5.7 V input signal range. The TTL-/CMOS-patible output stage is designed to drive up to 15 p F with full rated timing specifications and to degrade in a graceful and linear fashion as additional capacitance is added. The input stage of the parator offers robust protection against large input overdrive, and the outputs do not phase reverse when the valid input signal range is exceeded. The AD8469 is available in an 8-lead MSOP package and Features a shutdown pin and hysteresis control. It is fully specified over an operating temperature range of - 40°C to +125°C.
