AD1877JR

The AD1877JR is a stereo, 16-bit oversampling ADC based on Sigma Delta () technology intended primarily for digital audio bandwidth applications requiring a single 5 V power supply.Each single-ended channel consists of a fourth-order one-bit noise shaping modulator and a digital decimation filter.The AD1877JR antialias input circuit requires four external 470 pF NPO ceramic chip filter capacitors, two for each channel. No active electronics are needed. Decoupling capacitors for the supply and reference pins are also required.

The absolute maximum ratings of the AD1877JR can be summarized as:(1):the parameter is supply voltage,the rating is 5.0,the unit is V;(2):the parameter is ambient temperature,the rating is 25,the unit is ;(3):the parameter is input clock (FCLKIN) [256 * FS],the rating is 12.288,the unit is MHz;(4):the parameter is input signal,the rating is 991.768,the unit is Hz;(5):the parameter is input signal,the rating is -0.5,the unit is dB full scal;(6):the parameter is measurement bandwidth,the rating is 23.2 Hz to 19.998 kHz;(7):the parameter is load capacitance on digital outputs,the rating is 50,the unit is pF;(8):the parameter is input voltage HI (VIH),the rating is 2.4,the unit is V;(9):the parameter is input voltage LO (VIL),the rating is 0.8,the unit is V.
