Description

The TDA1543A is a monolithic integrated dual 16-bit digital-to-analog converter(DAC) designed as a low-cost-economy version for use in hi-fi digital audio equipment such as compact disc players, digital tape or cassete recorders, digital sound in television systems and digital amplifiers.

A Digital-to-Analog Converter (DAC) is an electronic device or integrated circuit that converts digital data, typically in the form of binary numbers, into analog voltage or current signals. This conversion process is essential in various applications where digital information needs to be translated into continuous analog signals. DACs are commonly used in audio systems, instrumentation, communication devices, and many other electronics applications.

The S6 version is a relaxed version of the TDA1543A. The differences in performance between the S6 selection and the standard version are limited to only three parameters :

Features

1. Low distortion

2. 16-bit dynamic range

3. 4 x oversampling possible

4. Single 5V power supply

5. No external components required

Description

The 7447 is  BCD to 7-Segment Decoder / Driver. The IC is a TTL (Transistor-Transistor Logic) integrated circuit (IC) that serves as a BCD (Binary-Coded Decimal) to 7-segment latch/decoder/driver. Its primary function is to take a 4-bit BCD input and convert it into the necessary control signals to drive a 7-segment display to represent decimal numbers.

The DM7446A and DM7447A feature active-LOW outputs designed for driving common-anode LEDs or incandescent indicators directly. All of the circuits have full ripple-blanking input/output controls and a lamp test input. Segment identification and resultant displays are shown on a following page. Display patterns for BCD input counts above nine are unique symbols to authenticate input conditions. All of the circuits incorporate automatic leading and/or trailing-edge, zero-blanking control (RBI and RBO). Lamp test (LT) of these devices may be performed at any time when the BI/RBO node is at a HIGH logic level.
