Audio Codec 1ADC / 1DAC 16-Bit 48-Pin LQFP T/R

The TLC320AD545 single channel data/fax codec is a mixed signal broadband connectivity device. The TLC320AD545 is comprised of a single channel codec and analog hybrid circuitry with a serial port for communication with the host processor. The device also contains programmable gain control and one AT41 speaker driver. The device operates with either a 5-V analog, a 5-V digital, and a 5-V monitor power supply or a 3.3-V analog, a 3.3-V digital, and a 3.3-V monitor power supply or 5-V analog, 3.3-V digital, and a 5-V monitor power supply. The device will be packaged in a single 48-pin PT (TQFP) package.
