It features two 24-bit conversion channels each with programmable gain amplifier (PGA), multibit sigma-delta modulator, and decimation filters. Each channel provides 105 db of dynamic range, making the AD1871 suitable for applications such as digital audio recorders and mixing consoles. Each of the AD1871’s input channels (left and right) can be configured as either differential or single-ended (two inputs muxed with internal single-ended-to-differential conversion). The input PGA features a gain range of 0 dB to 12 dB in steps of 3 dB. The Σ-∆ modulator features a proprietary multibit architecture that realizes optimum performance over an audio bandwidth with standard audio sampling rates of 32 kHz up to 96 kHz. The decimation filter response features very low pass- band ripple and excellent stop-band attenuation. The AD1871’s audio data interface supports all common interface formats such as I 2S, left-justified, right-justified as well as other modes that allow for convenient connection to general-purpose digital signal processors (DSPs). The AD1871 also features an SPI compatible serial control port that allows for convenient control of device parameters and functionality such as sample word-width, PGA settings, interface modes, and so on. The AD1871 operates from a single 5 V power supply—with an optional digital interfacing capability of 3.3 V. It is housed in a 28-lead SSOP package and is characterized for operation over the temperature range –40 °C to +105°C. |
