LTC1279CG#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1279CG#TRPBF is a 12-bit, 600ksps sampling A/D converter in a 24-lead SO Wide package. It operates from a single 5V or ±5V supply with typical power dissipation of 60mW and 8.5mW in shutdown mode. The device features an internal synchronized clock, a precision reference, and a flexible parallel interface. Key electrical parameters include a 600kHz maximum sampling frequency, 1.4μs conversion time, and 160ns acquisition time. AC performance specifies 70dB S/(N + D) at 100kHz input and ±1LSB INL/DNL linearity.

Analog To Digital Converters (ADC) Feature Summary

• Integrated sample-and-hold circuit with internal synchronized clock eliminates external clock noise issues.

• Power shutdown capability with instant wake-up reduces average power consumption during inactive periods.
• Internal reference can be overdriven externally to adjust input span.

Analog To Digital Converters (ADC) Applications

• High speed data acquisition systems
• Multiplexed data acquisition applications
• Digital signal processing interfaces
• Audio and telecom processing circuits

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific CG suffix indicates commercial temperature range (0°C to 70°C) and tape/reel packaging. Confirm the component matches the 24-lead SO Wide physical dimensions. Cross-reference the manufacturer's latest documentation for any lifecycle status changes or pinout revisions before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate resolution with high throughput and low power consumption. Ensure the analog input voltage remains within the specified unipolar or bipolar ranges relative to the chosen supply configuration. Verify that the driving amplifier can settle within the 160ns acquisition window to maintain accuracy.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1279 family of 12-bit successive approximation ADCs. It shares architectural similarities with other Linear Technology converters but is distinguished by its integrated clock and specific parallel interface timing. The CG variant specifically denotes the commercial temperature grade and surface-mount packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 12-bit resolution, 600ksps speed, and 24-pin SO Wide package. Verify compatibility with existing control logic timing requirements, particularly CONVST and RD signals. Check if alternative devices offer similar shutdown current levels and internal reference stability.
