Texas Instruments / Burr-Brown ADC80 Analog-to-Digital Converter

  • Industry-Standard 12-Bit ADC
  • ±0.012% Linearity
  • 25 µs Max Conversion Time
  • ±12V or ±15V Operation
  • No Missing Codes: -25°C to +85°C
  • Hermetic 32-Pin Package


The Texas Instruments / Burr-Brown ADC80 Analog-to-Digital Converter is a 12-bit successive-approximation analog-to-digital converter, utilizing state-of-the-art CMOS and laser-trimmed bipolar die custom designed for freedom from latch-up and optimum AC performance. It is complete with a comparator, a monolithic 12-bit DAC which includes a 6.3V reference laser-trimmed for minimum temperature coefficient, and a CMOS logic chip containing the successive approximation register (SAR), clock, and all other associated logic functions.

Internal scaling resistors are provided for the selection of analog input signal ranges of ±2.5V, ±5V, ±10V, 0 to +5V, or 0 to +10V. Gain and offset errors may be externally trimmed to zero, enabling initial endpoint accuracies of better than ±0.12% (±1/2LSB).

The maximum conversion time of 25µs makes the ADC80 ideal for a wide range of 12-bit applications requiring system throughput sampling rates up to 40kHz. In addition, the ADC80 may be short-cycled for faster conversion speed with reduced resolution, and an external clock may be used to synchronize the converter to the system clock or to obtain higher speed operation.

Data is available in parallel and serial form with corresponding clock and status signals. All digital input and output signals are TTL/LSTTL-compatible, with internal pull-up resistors included on all digital inputs to eliminate the need for external pull-up resistors on digital inputs not requiring connection. The ADC80 operates equally well with either ±15V or ±12V analog power supplies, and also requires use of a +5V logic power supply. However, unlike many ADC-type products, a +5V analog power supply is not required. It is packaged in a hermetic 32-pin side-brazed ceramic dual-in-line package.

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
