AD1877JRZ

AD1877 is a stereo, 16bit oversampling ADC based on Sigma Delta (∑∆) technology intended primarily for digital audio bandwidth applications requiring a single 5V power supply. Each single-ended channel consists of a fourth-order one-bit noise shaping modulator and a digital decimation filter. An on chip voltage reference, stable over temperature and time, defines the full-scale range for both channels. Digital output data from both channels are time-multiplexed to a single, flexible serial interface. Suitable for typical applications such as consumer digital audio receivers, digital audio recorders including portables CD-R, DCC, MD and DAT, multimedia and consumer electronic equipment, sampling music synthesizers, digital Karaoke systems.

• Single 5V power supply, single-ended dual-channel analog inputs
• 92dB (typ) dynamic range, 90dB (typ) S/(THD+N), 0.006dB decimator passband ripple
• Fourth-order, 64-times oversampling modulator
• 256 FS or 384 FS input clock
• Less than 100W (typ) power-down mode
• Input overrange indication, on-chip voltage reference
• Flexible serial output interface
• 28 pin SOIC package
• Operating temperature range from 0°C to 70°C
• Typical gain drift of 115ppm/°C
