LTC1279IG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1279IG#PBF 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.
• Flexible parallel interface with separate conversion start and data-ready signals simplifies DSP connections.
• Power shutdown capability with instant wake-up reduces average power consumption during inactive periods.
• Internal reference can be overdriven externally to adjust input span for unipolar or bipolar operation.

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 suffix IG#PBF against the manufacturer's current datasheet to confirm pinout compatibility and temperature range specifications. Ensure that the 24-lead SO Wide package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 600ksps throughput are required within a single-supply or dual-supply architecture. Consider the internal clock feature if minimizing external timing components is a priority. Evaluate the 60mW power dissipation against thermal constraints in dense packaging environments.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1279 family of successive approximation register ADCs. It shares architectural similarities with other high-speed converters but distinguishes itself through its integrated clocking and low-power shutdown modes. The industrial grade variant ensures reliable operation across extended temperature ranges compared to commercial equivalents.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must maintain 12-bit resolution, 600ksps sampling rate, and 24-pin SO Wide package. Verify pin-to-pin compatibility for control signals such as CONVST, RD, and CS. Check if alternative devices offer comparable S/(N + D) performance and similar power shutdown characteristics.
