LTC1279ISW#PBF

Analog To Digital Converters (ADC) Overview

The LTC1279ISW#PBF is a high-speed, 14-bit successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices. It operates on a single +5V supply and achieves a sampling rate of 200ksps with a typical power dissipation of 35mW. The device features an internal 2.5V reference and supports both unipolar and bipolar input ranges. It utilizes a parallel digital interface for data output and includes a shutdown mode that reduces current consumption to 1µA. The component is housed in a 24-lead SOIC package and is rated for operation within the industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer part number against official Analog Devices documentation to confirm specifications. Check RoHS compliance status via the datasheet. Confirm package type is 24-lead SOIC. Ensure operating temperature range meets application requirements of -40°C to +85°C.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 14-bit resolution and 200ksps speed are required with low power consumption. Compare with the LTC1278 (12-bit) or LTC1277 (12-bit, lower power) if resolution or power constraints differ. Ensure the parallel interface compatibility with the host microcontroller. Verify input voltage range matches the internal reference configuration.

Analog To Digital Converters (ADC) Part Context

The LTC1279 is part of the LTC127x family of 12-bit and 14-bit ADCs from Linear Technology (now Analog Devices). It shares architectural similarities with the LTC1278 and LTC1277 but offers higher resolution and speed. The 'ISW' suffix indicates the industrial temperature range and SOIC-24 package. The '#PBF' suffix denotes lead-free packaging compliant with RoHS standards.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements include other members of the LTC127x family such as the LTC1278 or LTC1277, depending on resolution and power requirements. Verify pinout compatibility and interface signals. Check if the alternative device meets the specific sampling rate and power dissipation needs.
