ADS6445IRGCT

The ADS6445IRGCT is a high-performance quad-channel 14-bit analog-to-digital converter (ADC) from Texas Instruments with a maximum sampling rate of 125 MSPS. It is part of the ADS644X family and features a pipeline architecture with simultaneous sample-and-hold inputs. The device provides serial LVDS data outputs to reduce the number of interface lines, enabling a compact 64-pin QFN package (9 mm × 9 mm).

Key specifications include a 500 MHz analog input bandwidth, 2 Vpp differential input voltage range, and typical power consumption of 1680 mW. The ADC achieves a signal-to-noise ratio (SNR) of 73.7 dB, spurious-free dynamic range (SFDR) of 87 dB, and effective number of bits (ENOB) of 11.7 bits. It supports an internal reference with optional external reference and can accept sine, LVCMOS, LVPECL, and LVDS clock inputs with amplitudes as low as 400 mVpp.

The device is designed for applications such as base-station IF receivers, diversity receivers, medical imaging, and test equipment. It operates from a 3.3V analog and digital supply over a temperature range of -40°C to 85°C. The ADS6445IRGCT is offered in a surface-mount 64-VFQFN exposed pad package (64-VQFN 9x9).
