XCR3128XL-10TQG144C 描述
The CS5381 uses a 5th-order, multi-bit delta-sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The ADC uses a differential architecture which provides excellent noise rejection.
XCR3128XL-10TQG144C 特点
OUT (Pin 1): Analog Output. In normal filtering, this is the output of an internal operational amplifier and is capable of swinging essentially to any voltage between the power supply rails (that is, between V+ and V C). This output is designed to drive a nominal load of 5k and 50pF. For lowest signal distortion it should be loaded as lightly as possible. The output can drive lower resistances than 5k, but distortion may increase, and the output current will limit at approximately 10mA. Capacitances higher than 50pF should be isolated by a series resistor of 500Ω to preserve AC stability. In the Mute state (F code 0000 or RST = 0), the output operates as in normal filtering but the gain from the IN pin becomes zero and the output noise is reduced. In the shutdown state (EN = 1 or EN open circuited), most of the circuitry in the XCR3128XL-10TQG144C shuts off and the OUT pin assumes a high impedance state.
