AS111

Rev. 1.6 6/05

Austin Semiconductor, Inc.

GENERAL DESCRIPTION

The AS111 is a voltage comparator that has input currents

nearly a thousand times lower than other similar devices like. It

is also designed to operate over a wider range of supply

voltages: from standard ±15V op amp supplies down to the

single 5V supply used for IC logic. Their output is compatible

with RTL, DTL and TTL as well as MOS circuits. Further, they

can drive lamps or relays, switching voltages up to 50V at

currents as high as 50 mA.

Both the inputs and the outputs of the AS111 can be

isolated from system ground, and the output can drive loads

referred to ground, the positive supply or the negative supply.

Offset balancing and strobe capability are provided and

outputs can be wire OR’ed. Although slower than some

devices (200 ns response time vs 40 ns), this device is also

much less prone to spurious oscillations.

FEATURES

• Operates from single 5V supply

• Input current: 150 nA max. over temperature

• Offset current: 20 nA max. over temperature

• Differential input voltage range: ±30V

• Power consumption: 135 mW at ±15V
