LTC1608AIG#PBF

Analog To Digital Converters (ADC) Overview

The LTC1608AIG#PBF is a high-speed, 16-bit sampling analog-to-digital converter (ADC) operating at 500ksps. It draws 270mW from ±5V supplies and features a differential input sample-and-hold with a –2.5V full-scale range. Key performance metrics include 90dB S/(N+D), –100dB THD, and 94dB SFDR. The device integrates a precision reference and offers two shutdown modes: Nap (7mW) and Sleep (10mW). It utilizes a 36-lead SSOP package and provides a microprocessor-compatible 16-bit parallel output interface without pipeline delay.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'I' suffix indicates an industrial temperature range of –40°C to +85°C. Confirm the '#PBF' suffix denotes lead-free packaging compliant with RoHS standards. Ensure the SSOP-36 package dimensions match the target PCB footprint. Check for availability as distribution status may vary by region.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption alongside high dynamic range. The internal 2.5V reference simplifies design but requires bypassing on Pin 3 and Pin 4. For single-ended inputs, ground AIN–. Ensure the driving amplifier settles within 200ns to maintain full throughput rates. The OVDD pin allows compatibility with 3V or 5V digital logic systems.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1608 family, which includes variants like the LTC1604. The 'A' grade typically specifies tighter linearity specifications compared to standard grades. The 'I' grade extends the operating temperature range to industrial levels. It is pin-compatible with other members of the series for board layout flexibility.
