Title:
DIFFERENTIAL AMPLIFIER
Document Type and Number:
Japanese Patent JPS59149408
Kind Code:
A
Abstract:
Differential amplifier with two inputs (E1, E2) which can be connected to two input voltage sources (U1, U2) and with two outputs (A1, A2) which can be connected to a consumer. Each of the two input voltage sources (U1, U2) can be connected by means of a first controllable switch device to each of the two inputs (E1, E2) and the consumer can be connected by means of a second controllable switch device (S5, S6) to each of the two outputs (A1, A2). The controllable switch devices (S1 to S6) can be connected by means of a switching clock generator (C) in such a way that, alternately and in each case with the same time duration, either the first input (E1) is connected to the first input voltage source (U1), the second input (E2) to the second input voltage source (U2) and the consumer to the first output (A1) or the first input (E1) to the second input voltage source (U2), the second input (E2) to the first input voltage source (U1) and the consumer to the second output (A2). A low-pass filter (TP) is connected between one output terminal (O) of the second controllable switch device (S5, S6) and the consumer to suppress the switching clock frequency.
