Sanyo LA7152 Specifications

Overview

The LA7152 is a three-input (clamped input) single-output
analog switch for video signals. The LA7152 high input
impedance structure allows 0.01 µF ceramic capacitors to
be used as the input coupling capacitors.

Features

• Three inputs - one output

• Built-in video clamping circuits

• Built-in muting function

Note: 1. Current drain

S1 = S2 = S3 = 2, S4 = S5 = S6 = 3

2. Maximum input level (input C = 10 µF)
S1 = 1, S4 = 1, S2 = S3 = 2, S5 = S6 = 3,
S2 = 1, S5 = 1, S1 = S3 = 2, S4 = S6 = 3,
S3 = 1, S1 = S2 = 2, S4 = S5 = S6 = 3
For each of the above three conditions, with an input signal frequency f = 1 kHz, gradually increase the input signal level and determine the level
where the total harmonic distortion reaches 0.1%.
