[development background]
In video signal processing circuits such as TVs and car navigation systems, there are many devices that use 1Vp-p amplitude to process signals. Therefore, the ADC*1 output signal amplitude in the circuit requires a video signal of 1Vp-p. However, the output of some DACs in the circuit is 0.7Vp-p. The current solution is to use a discrete component circuit to adjust the signal to 1Vp-p. Therefore, Nippon Wireless has developed the NJM41030, a gain adjustment IC.
*1 ADC: (Analog Digital Converter converts an analog signal into a digital signal.
ã€product Overview】
Feature 1 Contribute to high reliability and space saving of the machine. The gain adjustment circuit composed of the conventional discrete components is replaced by NJM41030, which reduces the number of parts and improves the reliability of the machine and saves 50%. Space.
Feature 2 achieves stable gain. In the past, the discrete component circuit was in a state of scattered instability depending on the impedance accuracy used. The NJM41030 can achieve stable gain.
