Analog Macro

We offer various analog macros (data converter, power management, temperature sensor, analog front-end) for our customers' development to address various applications including communication, image processing, sensors and control.

●All macros are silicon verified.

●Implemented on many custom SoCs with a track record in mass production.

Data Converters

We offer various data converter macros addressing low power consumption and a small area which are demanded in SoCs.

●Pipeline & high speed SAR ADC

  • 10-bit/12-bit resolution, maximum 200MSPS conversion rates
  • The world's smallest class power consumption

●Δ Σ ADC

  • Applicable to 16bit to 24bit resolutions
  • Power consumption of up to 1mW with high precision SINAD 85dB

●Δ Σ DAC

  • Applicable to 16bit to 24bit resolutions
  • SINAD 90dB. Power consumption is 1mW or less
