We offer various analog macros (ADC/DAC temperature sensor touch panel AFE DCDC LDO) to help our customers develop SoCs for challenging applications such as communication, image processing, sensors and control systems.
- All macros silicon verified.
- Implemented on many custom SoCs with records of volume production.
Data Converters
Our various data converter macros address the need for low power consumption and small area, with various process technologies.
High-speed SAR type ADC
- 10bit/12bit resolution, 600MS/s conversion rates.
- The smallest class power consumption in the world.
ΔΣ type ADC
- Applicable to 16bit - 24bit resolution.
- Power consumption of 1mW with the high precision of SINAD 85dB
ΔΣ type DAC
- Applicable 16bit - 24bit resolution.
- SINAD 90dB. Power consumption is 1mW or less
Power Management
Our power-management macros enable the single-power-supply development SoCs require, with various process technologies.
DC-DC converter for large-current-supply applications (switching regulator)
- Reduced cost achieved by consolidating power supply IC functions in SoCs
- 85% power conversion efficiency
- Safety protection functions such as short-circuit detection implemented
LDO for low-noise, power-supply applications (linear regulator)
