The TLV320AC40 and TLV320AC41 voice-band audio processor (VBAP) integrated circuits perform the transmit encoding (A /D conversion) and receive decoding (D/A conversion) together with transmit and receive filtering for voice-band communications systems. Cellular telephone systems are targeted in particular; however, these integrated circuits can function in other systems including digital audio, telecommunications, and data acquisition. These devices are pin-selectable for either of two modes companded and linear providing data in two formats. In the companded mode, data is transmitted and received in 8-bit words. In the linear mode, 13 bits of data, and either three bits of gain-setting control data, or three 0 bits of padding (to create a16-bit word), are sent and received. The transmit section is designed to interface directly with an electret microphone element. The microphone input signal (MICIN) is buffered and amplified with provision for setting the amplifier gain to accommodate a range of signal input levels. The amplified signal is passed through antialiasing and bandpass filters. The filtered signal is then applied to the input of a compressing analog-to-digital converter (COADC) when companded mode is selected. Otherwise, the analog-to-digital converter performs a linear conversion. The resulting data is then clocked out of DOUT as a serial data stream. The receive section converts a frame of serial data on DIN to analog through an expanding digital-to-analog converter (EXDAC) when the companded mode is selected; otherwise, a linear conversion is performed. The analog signal then passes through switched capacitor filters, which provide out-of-band rejection, (sin x)/x correction functions, and smoothing. The filtered signal is sent to the earphone amplifier. The earphone amplifier has a differential output with adjustable gain and is designed to minimize static power dissipation. A single on-chip high-precision band-gap circuit generates all voltage references, eliminating the need for external reference voltages. An internal reference voltage, VMID, equal to VCC /2 is used to develop the midlevel virtual ground for all the amplifier circuits and the microphone bias circuit. Another reference voltage, MICBIAS, can supply bias current for the microphone. The TLV320AC4xC devices are characterized for operation from to 70°C. The TLV320AC4xI devices are characterized for operation from to 85°C.
