SAM1600 Family:  8 and 16 Channel 12-bit 65 Msample/sec ADCs with Prism™ Compression

Overview

The SAM1600 is an innovative family of true 16-channel, 12-bit, 65 MSPS analog-to-digital converter (ADC) ICs with integrated data compression technology. The SAM1600 family boasts industry-leading power consumption in a 16-channel, 12-bit device of just 44 mW per channel. The performance of the SAM1600 family is further enhanced by the integration of Samplify’s patented PrismTM data compression technology which reduces the number of LVDS I/O pairs (in some applications from 16 pairs to as few as 4), and thereby the power they consume, by up to 75% for high channel density applications.
The SAM1600 family includes the SAM1610, SAM1605, and SAM1600:
The 16-channel SAM1610 and 8-channel SAM1605 combine 12-bit, 45/65 MSPS ADCs with Samplify’s patented PrismTM signal compression and patent-pending port concentration technology.
The SAM1610/00 have 16 truly independent ADC channels, keeping crosstalk below the noise floor of the ADC. In contrast, the SNR performance of pseudo-16 channel devices, which time-share an ADC across two analog input channels, is limited by crosstalk.
For systems not yet ready to exploit the benefits of compression, Samplify offers the SAM1600 in a traditional ADC configuration, allowing designers to take full advantage of the SAM1600’s higher channel density and lower power. The SAM1600 can also be configured as two independent octal ADCs with separate frame and clock outputs to maintain compatibility with legacy FPGA or ASIC designs.
