Features

• Operation with wide power supply voltage range from 2.1 V to 6.0 V
• Enlargement of dynamic range by incorporating a vari- able VREF circuit that varies according to the supply voltage
• Possible to adjust the received voice attenuation amount with an external resistor
• Possible to adjust the AGC operating point with an external resistor
• Possible to design with fewer external components 0.1ae±n0.1dc 1.27e0.6 ± 0.3/ 0.4 ± 0.25 5.0 ± 0.3 lifecycle 0.15 0.65 stage. Unit: mm 18 27 36 45 0.3 4.2 ± 0.3 6.5 ± 0.3 SOP008-P-0225A 1.5 ± 0.2 s Block Diagram VREF Det. CC Buff P4321lehtatsp:e.
