10 bit multiplication analog-to-digital converter GX7533 benchmarking AD7533 applied to CNC attenuator

Numerical control attenuator is a microwave/RF/high-speed analog device manufactured based on semiconductor technology or MEMS technology. Its core function is to provide precise and controllable signal amplitude attenuation on the signal path based on external input digital control words. Generally used in communication systems, audio equipment, power amplifiers, and other fields.

The CNC attenuator is composed of input signal reception, control signal processing, and output signal adjustment. The 10 bit high-resolution of the domestically produced multiplication digital to analog converter GX7533 can achieve precise attenuation adjustment of the CNC attenuator. GX7533 is flexible in application, compatible with TTL and CMOS interfaces, powered by a 5V to 15V power supply, and provides appropriate binary offset for positive or negative reference inputs.

GX7533 has the following characteristics:

1. GX7533 is a low-cost, 10 bit 4-quadrant multiplying DAC manufactured using advanced single-chip thin-film CMOS technology.

2. Multi channel output: full four quadrant multiplication converter, no latch (no need for Schottky diode protection);

3. Wide voltage range: powered by a 5V to 15V power supply, and providing appropriate binary offset for positive or negative polarity reference inputs;

4. Low power consumption: Low operating power consumption, operating temperature range of -45 ℃ -125 ℃;

5. Multiple serial port compatibility: compatible with TTL and CMOS interfaces, easy to design;

6. Support power down mode: With power down mode, it can optimize power consumption during operation.

7. GX7533 can be used in CNC attenuators, programmable gain amplifiers, function generators, linear automatic gain control, and other applications, fully compatible with AD7533.
