LTC1418AIN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1418AIN#PBF is a low power, 14-bit successive approximation register (SAR) analog-to-digital converter with a sampling rate of 200ksps. It operates from a single 5V or ±5V supply and features selectable serial or parallel data output formats. The device integrates a high-performance sample-and-hold circuit, a precision reference, and internal timing to minimize external component requirements. Key electrical specifications include ±1.25LSB maximum integral nonlinearity (INL), ±1LSB differential nonlinearity (DNL), and no missing codes over the operating temperature range. Power dissipation is typically 15mW, supported by two user-selectable shutdown modes.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the ordering suffix 'N' corresponds to the 28-lead narrow PDIP package as specified in the manufacturer's order information table. Confirm the 'A' grade designation for the specific linearity performance limits required by the design. Ensure compatibility with the industrial temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 14-bit SAR ADC with low power consumption and flexible I/O options is required. The LTC1418AIN#PBF supports both unipolar (0V to 4.096V) and bipolar (±2.048V) input ranges. Consider the 28-lead narrow PDIP package constraints for PCB layout. Verify that the source impedance driving the analog inputs allows for the specified 1µs acquisition time at full throughput.

Analog To Digital Converters (ADC) Part Context

The LTC1418AIN#PBF belongs to the LTC1418 family of low-power, 14-bit, 200ksps ADCs. The 'A' suffix indicates enhanced linearity specifications compared to the standard 'C' grade, while 'I' denotes the industrial temperature range. The 'N' suffix identifies the 28-lead narrow plastic dual in-line package (PDIP). This part is designed to replace older generation ADCs requiring external references and clocks.
