LTC2383CDE-16#PBF

Analog To Digital Converters (ADC) Overview

The LTC2383CDE-16#PBF is a 16-bit, 1Msps successive approximation register (SAR) analog-to-digital converter manufactured by Analog Devices Inc. It operates from a single 2.5V supply and features a ±2.5V fully differential input range. The device consumes 13mW at full throughput and achieves a typical SNR of 92dB with no missing codes at 16 bits. It utilizes an SPI-compatible serial interface supporting 1.8V to 5V logic levels and includes daisy-chain capability. The component is housed in a 16-lead (4mm × 3mm) plastic DFN package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix #PBF indicates lead-free finish and tube packaging. Confirm the DE suffix corresponds to the 16-lead (4mm × 3mm) plastic DFN package. Ensure the temperature grade matches application requirements, as this part number specifies the C-grade operating range of 0°C to 70°C.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring high speed and low power simultaneously. The internal oscillator simplifies timing design. Ensure the external reference voltage is within the 2.4V to 2.6V range. For temperatures exceeding 70°C, consider the I-grade or H-grade variants. The differential input requires appropriate driving circuitry to maintain performance.

Analog To Digital Converters (ADC) Part Context

This component belongs to the LTC238X-16 SAR ADC family. It offers higher throughput than the LTC2382-16 (500ksps) and LTC2381-16 (250ksps), which consume 6.5mW and 3.25mW respectively. All family members share 16-bit resolution but differ in sampling speed and power dissipation profiles.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include other members of the LTC238X-16 family such as the LTC2382CDE-16#PBF for lower speed/power needs. Cross-family replacements require verification of pin compatibility and electrical specifications against the original datasheet.
