LTC2158CUP-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2158CUP-14#PBF is a dual-channel, 14-bit simultaneous sampling analog-to-digital converter (ADC) operating at a maximum sampling rate of 310Msps. It features a pipeline architecture with DDR LVDS digital outputs and requires a single 1.8V supply. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 68.8dBFS and an Spurious Free Dynamic Range (SFDR) of 88dB. The device offers low power consumption of 724mW, an easy-to-drive 1.32VP-P differential input range, and a full-power bandwidth of 1.25GHz. It includes an internal reference, optional clock duty cycle stabilizer, and serial SPI configuration.

Analog To Digital Converters (ADC) Procurement Notes

Verify the 'C' suffix indicates the commercial temperature range (0°C to 70°C). Confirm the '#PBF' designation specifies lead-free finish and tube packaging. Ensure the source document explicitly identifies Analog Devices Inc. as the manufacturer for this specific part number.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high-speed digitization of wide dynamic range signals. The 1.32VP-P input range simplifies drive circuit design. Consider the 6-cycle pipeline latency and DDR LVDS output interface requirements when designing the system logic. Verify that the 724mW power dissipation fits within the thermal constraints of the 64-lead QFN package.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2158-14 family of high-speed ADCs. It is pin-compatible with a 12-bit version of the same series. The device utilizes a 64-lead (9mm × 9mm) plastic QFN package with an exposed ground pad that must be soldered to the PCB.
