AD/DA CONVERTER

MB40166/MB40176

1-CHANNEL 6-BIT AD/DA CONVERTER WITH CLAMP

CIRCUIT

The Fujitsu MB40166 and MB40176 are low power 6-bit AD/DA converter which

is fabricated with Fujitsu Advanced Bipolar Technology. MB40166 and MB40176

have the same basic circuits and functions, with the only difference being that

MB40166 has an independent analog input terminal for the A/D section and a

clamp voltage output terminal, while MB40176 has an analog input in the A/D

section internally connected with the clamp circuit.

Since both models contain a single-chip clamp circuit and a reference voltage

circuit, they are ideal for video signal processing.

NOTE: Permanent device damage may occur if the aboveAbsolute Maximum

Ratings are exceeded. Functional operation should be restricted to the

conditions as detailed in the operational sections of this data sheet.

Exposure to absolute maximum rating conditions for extended periods

may affect device reliability.

This device contains circuitry to protect the inputs against

damage due to high static voltages or electric fields. However,

it is advised that normal precautions be taken to avoid

application of any voltage higher than maximum rated voltages

to this high impedance circuit.
