Features

The cascade connection terminal makes configuration expansion easy.

When using several D / A converters at the same time, additional control wires must either be installed or set to each D / A converter. The cascade connection method is best suited for applications that require as many channels as possible. By attaching the cascade connecting DATA output terminal to the DATA input terminal, multiple D / A converters can be treated as a single multi-channel D / A converter, eliminating the need to install a microcontroller CPU control port or harness. The shared interface configuration (4 bits+10 bits) allows the user to combine devices that have a different number of channels.
*For cascade connection, please ensure that the clock line is as short as possible in order to maximize the margin between the data transmission and clock edge.

The 10bit resolution and range-variable function are ideal for canceling the offset from small signal amplifiers.
Rapid, accurate adjustment for quick stability
High frequency compatibility (10MHz) allows the microcontroller to operate at maximum speed.
TTL support allows direct connection to a 3V microcontroller
