LTC1406CGN#PBF

Analog To Digital Converters (ADC) Overview

The LTC1406CGN#PBF is a low-power, 8-bit, 20Msps sampling A/D converter housed in a 24-lead narrow SSOP package. It operates from a single 5V supply with typical power dissipation of 150mW at full throughput. The device features a high dynamic range sample-and-hold with a 250MHz bandwidth and true differential inputs providing 60dB common mode rejection. Key electrical specifications include ±1LSB maximum DNL and INL, a ±1V differential input span, and a five-clock-cycle pipeline latency. It supports interface to 3V digital systems via separate output supplies.

Analog To Digital Converters (ADC) Procurement Notes

Verify the ordering suffix #PBF indicates lead-free RoHS compliance. Confirm the CGN suffix corresponds to the commercial temperature range (0°C to 70°C) and the 24-lead SSOP package. Ensure the source document matches the manufacturer Analog Devices Inc. for the part number LTC1406CGN#PBF.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring low power consumption and moderate resolution at high speeds. The differential input architecture allows for flexible single-ended or differential driving configurations. Ensure the system clock provides a 50% duty cycle with fast rise/fall times (<2ns) to maintain performance at 20Msps. Verify that the OVDD supply voltage aligns with the target digital logic levels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC1406 family of sampling ADCs. The 'C' grade denotes the commercial operating temperature range, while 'I' grades cover industrial temperatures. The 'GN' designation specifies the plastic SSOP package. The '#PBF' suffix confirms the material composition meets lead-free standards.
