VQFN (RGZ)-48-49 mm² 7 x 7
The ADS556x is a high-performance 16-bit family of ADCs with sampling rates up to 80 MSPS. The device supports very-high SNR for input frequencies in the first Nyquist zone. The device includes a low-frequency noise suppression mode that improves the noise from DC to about 1 MHz.
In addition to high performance, the device offers several flexible features such as output interface (either Double Data Rate [DDR] LVDS or parallel CMOS) and fine gain in 1-dB steps until 6-dB maximum gain.
Innovative techniques, such as DDR LVDS and an internal reference that does not require external decoupling capacitors, have been used to achieve significant savings in pin count. This innovation results in a compact 7-mm × 7-mm 48-pin VQFN package.
The device can be put in an external reference mode, where the VCM pin behaves as the external reference input. For applications where power is important, the ADS556x device offers power down modes and automatic power scaling at lower sample rates.
The device is specified over the industrial temperature range of 40°C to 85°C.
