AD9246BCPZ-105

The AD9246BCPZ-105 is a 14-bit, 105 MSPS analog-to-digital converter (ADC) from Analog Devices, part of the AD9246 series. It uses a multistage differential pipeline architecture with output error correction logic to provide 14-bit accuracy at high data rates. The device operates from a 1.8 V analog supply and a 1.8 V to 3.3 V output supply, with typical power consumption of 458 mW at 105 MSPS.

Key electrical performance includes a signal-to-noise ratio (SNR) of 71.7 dBc (72.7 dBFS) and a spurious-free dynamic range (SFDR) of 85 dBc, both measured with a 70 MHz input. The differential nonlinearity (DNL) is ±0.4 LSB typical, and the integral nonlinearity (INL) is ±1.3 LSB typical. The analog input bandwidth is 650 MHz, and the input voltage range is 2 V p-p.

The ADC is housed in a 48-lead LFCSP package (7x7 mm) with an exposed pad, suitable for surface mount assembly. It operates over a temperature range of -40°C to +85°C. The device includes an on-chip voltage reference and sample-and-hold amplifier, and supports offset binary, Gray code, or twos complement data output formats.
