It datazheet recommended to re-write all registers after a line-break, as a line break may take long enough to discharge VDD, even when the MASK bit datzsheet set. Each register has 4 bit data width.

Two voice controlled attenuators prevent acoustic coupling between the loudspeaker and the microphone. The soft clip circuit limits the output voltage at LO to 1. In receive mode the attenuation of the receive path and the transmit path can be controlled by Register Handsfree receive end gain between 0dB and dB.

Applications requiring extended temperature range, unusual environmental requirements, or high reliability applications, such as military, medical life-support or life-sustaining equipment are specifically not recommended without additional processing by austriamicrosystems AG for each application.

V LI can be programmed to be 3. Analog tone at RO This product is intended for use in normal commercial applications. AS Interface – Telecom. Copy your embed code and put on your site: Digital as253 control of Rx signals on AS only. As25223 datasheet and specification datasheet.

Dual softclipping in handsfree mode on AS only. The user can also change the gain via Register Handsfree receive end gain See section “Handsfree”.


However, electromagnetic pulses on the clock and data lines may cause unwanted programming of the chip. All products and companies mentioned are trademarks of their respective companies. Rx-volume control for handset and handsfree operation. No Conf Tone Therefore, prior to designing this product into a system, it is necessary to check with austriamicrosystems AG for current information.

Loudspeaker amplifier for loudhearing and handsfree. There is LLC for this path. The as523 operating mode is from 15mA to mA. Typical mean values will not be tested. Mask, Lh, Hf, Hook Mask: Internal pull-up resistor kOhm The soft clip circuit limits eatasheet output voltage at LS to 2V p. The information furnished here by austriamicrosystems AG is believed to be correct and accurate.

The first four bits 7,6,5,4 are the addresses of the registers, the last four bits 3,2,1,0 are the data bits. Disclaimer Devices sold by austriamicrosystems AG are covered by the warranty and patent identification provisions appearing in its Term of Sale. Datashet review product page below for detailed information, including AS price, datasheets, in-stock availability, technical difficulties.

Other settings do not need to be re-written, as VDD has not discharged. Rx-offset setting 0 0 0mV 0 1 12mV 1 0 40mV 1 1 mV One can adapt side tone without changing the ACimpedance.


Side tone adaptation selectable by external components. No obligation or liability to recipient or any third party shall arise or flow out of austriamicrosystems AG rendering of technical or other services. Elcodis is a trademark of Elcodis Company Ltd.

Applications Enhanced handsfree feature phones with CallerID and extended displays.

AS & AS Single Chip Phone – Audio | PMT

Applications Enhanced handsfree feature phones with CallerID and extended displays The soft clip circuit limits the output voltage at RO to 1V p. Line datasbeet compensation setting 0 0 20mAmA Line loss compensation 1 0 mA Line loss compensation Re-writing all registers also eases later software updates, as only register contents need to be changed, but no additional command lines need to be inserted.

For factory test only! The first four bits 7,6,5,4 are the addresses of the registers, the last four bits 3,2,1,0 are the data bits. This guarantees safe operation in case of unexpected loss of power during normal operation. This provides a maximum of independence of AC-impedance and side tone from each other.
