108 dB, 192 kHz Stereo ADC

The CS5351 is a complete analog to digital converter for digital audio systems. It performs sampling, analog to digital conversion, and anti-alias filtering. The device generates 24-bit values for both left and right inputs in serial form at sample rates up to 192 kHz per channel. The CS5351 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...

4-channel Microphone ADC with TDM Interface

The CS53L30 is a high-performance, low-power, quad-channel ADC. It is designed for use in multiple-mic applications while consuming minimal board space and power. The flexible ADC inputs can accommodate four channels of analog mic or line-input data in differential, pseudo differential, or single-ended mode, or four channels of digital mic data. The analog input path includes a +10 to +20 dB boost and a -6 to +12 dB PGA. Digital mic data bypasses the analog gain circuits and is fed directly to...

3.3V Dual Channel Analog Front End

The MCP3911 is a 2.7V to 3.6V dual channel Analog Front End (AFE) containing two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC), two PGAs, phase delay compensation block, internal voltage reference, modulator output block, and highspeed 20 MHz SPI compatible serial interface. The MCP3911 is capable of interfacing a large variety of voltage and current sensors including shunts, current transformers, Rogowski coils and Hall effect sensors. *Features* * Two Synchronous...

High Linearity 2-Channel ADC

The ADS42JB46 is a high-linearity, dual-channel, 14-bit, 160-MSPS, analog-to-digital converter (ADC). This device supports the JESD204B serial interface with data rates up to 3.125 Gbps. The buffered analog input provides uniform input impedance across a wide frequency range while minimizing sample-and-hold glitch energy, thus making driving analog inputs up to very high input frequencies easy. A sampling clock divider allows more flexibility for system clock architecture design. The device...

Multi-Bit A/D for Class-D Real-Time PSR Feedback

The CS4461 is a complete analog to digital converter for class-D real time power supply rejection (PSR) feedback. It performs sampling and ADC, generating digital data for input to a class-D modulator with real-time PSR feedback. The CS4461 uses a 5th-order, multi-bit delata-sigma modulator followed by output data formatting. The ADC uses a differential architecture which provides excellent noise rejection. *Features* * Advanced Multi-bit Delta Sigma Architecture * Real-time Feedback of Power...

11-bit Dual ADC Serial Interface

The ADC1113D125 is a dual channel 11-bit Analog to Digital Converter (ADC) optimized for high dynamic performance and low power at a sample rate of 125 Msps. Pipelined architecture and output error correction ensure the ADC1113D125 is accurate enough to guarantee zero missing codes over the entire operating range. Supplied from a 3 V source for analog and a 1.8 V source for the output driver, it embeds two serial outputs. Each lane is differential and complies with the JESD204A. A set of IC...

Multi-Bit Audio A/D Converter

The CS5342 is a complete analog-to-digital converter for digital audio systems. It performs sampling, analog-to-digital conversion and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel. The CS5342 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 CS5342 is available in a 16-pin TSSOP package in...

Low-Power Low-Noise 24-Bit ADC

The ADS1220 is a precision, 24-bit, analog-to-digital converter (ADC) offered in a leadless QFN-16 or a TSSOP-16 package. The device features two differential or four single-ended inputs through a very flexible input multiplexer (mux), a low-noise, programmable gain amplifier (PGA), two programmable excitation current sources, an internal reference, an oscillator, a low-side bridge switch, and a precision temperature sensor. The many integrated features and the simple control of the ADS1220...
