LTC2207IUK-14#PBF

Analog To Digital Converters (ADC) Overview

The LTC2207IUK-14#PBF is a 14-bit, 105Msps analog-to-digital converter (ADC) from Analog Devices. It features a pipeline architecture with an internal reference generator and a programmable gain amplifier (PGA). The device operates on a single 3.3V supply, dissipating 947mW at full speed. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 77.3dBFS, a Spurious Free Dynamic Range (SFDR) of 98dB, and an integral nonlinearity (INL) of ±1.5LSB. It utilizes a 48-lead 7mm × 7mm QFN package and supports an operating temperature range of –40°C to 85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component against the official Analog Devices datasheet (220714614fd.pdf) to confirm pinout compatibility and electrical parameters. Ensure the specific IUK suffix matches the required 48-lead QFN package dimensions and thermal characteristics for the target PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this model when high-speed digitization up to 105Msps is required with low power consumption. The integrated PGA allows optimization for input signals ranging from 1.5VP-P to 2.25VP-P. Consider the 7-cycle pipeline latency and CMOS output swing capabilities (0.5V to 3.6V via OVDD) for interface matching.

Analog To Digital Converters (ADC) Part Context

This part belongs to the LTC2207-14/LTC2206-14 family of high-speed ADCs. It is pin-compatible with other variants in the series, such as the 16-bit LTC2207 and the 80Msps LTC2206-14, facilitating design scalability across different resolution and speed requirements within the same package footprint.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the LTC2207 (16-bit, 105Msps), LTC2206-14 (14-bit, 80Msps), and LTC2205-14 (14-bit, 65Msps). Verify that the sampling rate and bit-resolution differences meet the system requirements before substitution.
