High Performance 2ch 1bit 10MHz ΔΣModulator Is Suitable for Output Stage of a Current Sensor; The AK9223 Is Now On The Market.

【Product Name】

AK9223MK
【Title】

2ch 1bit, 10MHz, ΔΣModulator
【Application】
Motor Controllers, Current Sensors, Industrial Equipment Sensors

【Description】

Since the market demand for small current sensor with high insulation characteristics for industrial motors and energy meters, AKM has developed the AK9223MK a high performance A/D converter for the output stage of a current sensor.

The AK9223MK is a 2ch delta-sigma modulator that operates by a 10MHz internal clock. It is capable to achieve a high performance current measurement with a digital low-pass filter at the output.


High S/N Performance

The AK9223MK achieves 92dB S/N performance based on AKM's accumulated experience and know-how in analog-digital mixed signal LSI technology.


High Accuracy VREF, Internal Clock

VREF is 2.5V±1%, and internal clock frequency is 10MHz±10%.
