GENERAL DESCRIPTION
The AD1803 is a low power, 16-bit codec for modem, voice/handset, and telephony applications. It can also be used as a cellular telephone interface.
The AD1803 is an Intel AC 97 Rev 2.1-compliant modem codec (refer to documentation about the Intel AC 97) with selectable AC 97 or a DSP-style serial interface.
The AD1803 codec uses high performance Σ-Δ ADCs and DACs with programmable gain/attenuation. It has a digital Σ-Δ monitor output with selectable mix from ADC and DAC channels for call progress monitoring.
The AD1803 supports advanced power management with several power saving modes. The codec supports seven general purpose input/output (GPIO) pins and a wake interrupt signaling mechanism on GPIO events.
The AD1803JRUZ is a lead-free environmentally friendly product. It is manufactured using the most up-to-date mate rials and processes. The coating on the leads of each device is 100 pure tin electroplate. The device is suitable for lead-free applications and can withstand surface-mount soldering at up to 255°C (±5°C). In addition, it is backward compatible with conventional tin-lead soldering processes. This means that the electroplated tin coating can be soldered with tin-lead solder pastes at reflow temperatures of 220°C to 235°C.
