HA17903A

HA17903A Series Dual Comparators REJ03D0807-0100 Rev.1.00 Mar 10, 2005 Description The HA17903A series products are comparators designed for general purpose, especially for power control systems. These ICs operate from a single power-supply voltage over a wide range of voltages, and feature a reduced powersupply current since the supply current is independent of the supply voltage. These comparators have the merit which ground is included in the common-mode input voltage range at a singlevoltage power supply operation. These products have a wide range of applications, including limit comparators, simple A/D converters, pulse/square-wave/time delay generators, wide range VCO circuits, MOS clock timers, multivibrators, and high-voltage logic gates. Features Wide power-supply voltage range : 2 to 36 V Very low supply current : 0.8 mA Typ. Low input bias current : 25 nA Typ. Low input offset current : 3 nA Typ. Low input offset voltage : 2 mV Typ. The common-mode input voltage range includes ground Output voltages compatible with CMOS logic systems Rev.1.00 Mar 10, 2006 page 1 of 8 HA17903A Series Low electro-magnetic susceptibility Measurement Condition Vcc = 5 V Vcc 1k + 5.1 kΩ 1k − Vout Vin 1 V 0.01 µF −10 dBm RF signal source (for quasi-RF noise) Vout (V) Vout (V) 6.0 5.0 4.0 3.0 2.0 1.0 0.0 −1.0 0.85 6.0 5.0 4.0 3.0 2.0 1.0 0.0 −1.0 0.85 HA17903A Vout vs. Vin HA17903A (0 Hz) HA17903A (10 MHz) HA17903A (100 MHz) 0.90 0.95 1.00 1.05...
