Sanyo LA7152 Specifications

Ordering number : EN4955

Monolithic Linear IC

LA7152

VCR Electronic Switch

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%.

3.Frequency characteristics

For each of the three conditions in Note 2,

VIN = 2.0 Vp-p, VOUT (5 MHz)/VOUT (100 KHz)

4.Total harmonic distortion (input C = 10 µF)

For each of the three conditions in item 2, measure the total harmonic distortion with VIN = 2.0 Vp-p and f = 1 kHz.

5.Crosstalk

With S6 = 3, measure in the modes for all combinations of S1 to S5 except for the following three conditions: a) S1 = S4 = 1, b) S2 = S5 = 1 and c) S3 = 1, S4 = S5 = 3.

VIN = 2.0 Vp-p, f = 4.43 MHz, VOUT/VIN

6.Muting circuit crosstalk

With S6 = 1, measure in the modes for all combinations of S1 to S5. VIN = 2.0 Vp-p, f = 4.43 MHz, VOUT/VIN

7.Output DC offset

Measure the output DC voltage difference between the following modes with S1 = S2 = S3 = 2.

a.S4 = 1, S5 = S6 = 3

b.S5 = 1, S4 = S6 = 3

c.S4 = S5 = S6 = 3

d.S6 = 1, S4 = S5 = 1 or 2
