Analog To Digital Converters (ADC) datasheet and documents for LTC1278-4CSW#TRPBF

LTC1278-4CSW#TRPBF

Analog To Digital Converters (ADC) Overview

The LTC1278-4CSW#TRPBF is a 12-bit, 400ksps sampling analog-to-digital converter in a 24-lead SOIC (SW) package. It operates from a single +5V or dual ±5V supply, consuming 75mW during conversion and 8.5mW in shutdown mode. The device integrates a 200ns sample-and-hold, a precision 2.42V reference, and an internally trimmed clock. Key electrical specifications include ±1LSB INL/DNL, 70dB S/(N+D), and 78dB THD at 100kHz input frequency.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-4 for 400ksps) against design requirements. Confirm the SW package variant matches PCB footprint constraints. Ensure supply voltage conditions align with unipolar (+5V) or bipolar (±5V) operation modes specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring moderate speed (400ksps) and high linearity (±1LSB). Consider the LTC1278-5 if higher throughput (500ksps) is needed. Evaluate power consumption needs; the shutdown mode reduces dissipation to 8.5mW. Ensure the analog input range (0-5V or ±2.5V) matches the signal source.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1278 family of 12-bit sampling ADCs. The -4 suffix denotes the commercial grade speed bin limited to 400ksps maximum sampling rate. The CSW suffix indicates the 24-lead plastic SOIC wide package. It serves as a cost-effective solution for general-purpose high-speed conversion tasks.
