Special-Purpose Analog-to-Digital Converters (ADCs)

Perform Dedicated Functions With Special-Purpose ADCs

Special-purpose Analog-to-Digital Converters (ADCs) perform dedicated functions such as dual-slope conversion, voltage-to-frequency conversion, frequency-to-voltage conversion, and 3½-digit Binary-Coded Decimal (BCD) and binary conversion. You can combine these devices with other functions such as driving Liquid Crystal Displays (LCDs) or Light Emitting Diodes (LEDs).

We offer ADCs within the dual-slope community that include noise rejection of 50/60 Hz and flexible tradeoffs between conversion speed and resolution. As a result, these devices are suitable for a variety of data acquisition systems such as precision analog signal processors, sensor interfaces, high-accuracy DC measurements, computer peripheral interfaces, portable instruments and more.

In addition, we offer low-power, high-performance, monolithic CMOS 3 ½-digit ADCs that function between BCD and binary converters. Each high-precision converter offers industry-standard interfaces and pinouts that make these devices well suited for applications such as sensor interfaces, process controls, panel meters, instrumentation and more.

Integrated ADCs Versus Stand-Alone ADCs

The importance of Analog-to-Digital Converters (ADCs) is growing, leaving the designer forced to evaluate whether they should choose a microcontroller with an integrated ADC to meet their system requirements or if they should use a standalone ADC. In this episode of Coffee Break, we will discuss the difference between integrated and standalone ADCs.
