AD7952 datasheet

Описание :

The AD7952 is a 14-bit, charge redistribution, successive approximation register (SAR) architecture analog-to-digital converter (ADC) fabricated on Analog Devices, Inc.’s iCMOS high voltage process. The device is configured through hardware or via a dedicated write-only serial configuration port for input range and operating mode. The AD7952 contains a high speed 14-bit sampling ADC, an internal conversion clock, an internal reference (and buffer), error correction circuits, and both serial and parallel system interface ports. A falling edge on CNVST samples the fully differential analog inputs on IN+ and IN−. The AD7952 features four different analog input ranges and three
different sampling modes: warp mode for the fastest throughput, normal mode for the fastest asynchronous throughput, and impulse mode where power is scaled with throughput. Operation is specified from −40°C to +85°C.

MSP3415G datasheet

Описание :

1. Introduction
The MSP 34x5G family of single-chip Multistandard Sound Processors covers the sound processing of all
analog TV standards worldwide, as well as the NICAM digital sound standards. The full TV sound processing,
starting with analog sound IF signal-in, down to processed analog AF-out, is performed in a single chip.
Figure 1–1 shows a simplified functional block diagram of the MSP 34x5G.

These TV sound processing ICs include versions for processing the multichannel television sound (MTS)
signal conforming to the standard recommended by the Broadcast Television Systems Committee (BTSC).
The DBX noise reduction, or alternatively, Micronas Noise Reduction (MNR) is performed alignment free.
