12-bit 65MS/s Dual Input ADC
The 12-bit Dual Input ADC is a low-power 12-bit dual input ADC IP with a core sampling rate from 25MS/s up to 65MS/s.
The ADC employs a high-performance dual input sample-and-hold (S/H) circuit together with a differential pipeline architecture and digital error correction.
The dual input architecture enables this single ADC to be used as a complete IQ ADC solution. In this configuration, both S/H circuits are used and the single ADC core converts each channel alternately, thereby enabling very high channel-to-channel matching and minimum die area in IQ applications.
For maximum flexibility, the power dissipation of the ADC scales with the sampling frequency.
This 12-bit ADC features an excellent static performance that includes ±0.5LSB DNL and ±2.5LSB INL typ.
Dynamic performance highlights considering an input signal with 10MHz frequency, 65MS/s sampling rate for ADC core and 32.5MS/s sampling rate per channel, include SNR of 64dB, SFDR of 72dB and SNDR of 63dB, yielding 10.2ENOB performance.
Auxiliary circuits comprising a bandgap, frequency-dependent current biasing and internal reference buffers are also included.
The S3AD65MD12BT55 does not require any special analog options, and can be cost-effectively ported across foundries and process nodes upon request.
