We’re excited to announce the tapeout of our latest data converter: a dual 750MS/s, 11-bit ADC, built on 28HPC+ TSMC technology. This chip is the perfect counterpart to our 1GS/s DAC series, making it an ideal fit for modern mixed-signal systems.
What sets this ADC apart?
- Single 1V Supply: The entire chip runs on just 1 V.
- Pipeline Architecture: High-speed, high-accuracy 11-bit resolution.
- Flexible Clocking: The two ADCs can be operated:
- In phase (0°/0°)
- As IQ pairs (0°/90°)
- Or time-interleaved (0°/180°) for even higher effective sampling rates.
- Fine-Grained Phase Control: Clock phase control between the 2 ADCs with 150 fs step size to mitigate timing mismatch.
- True 1V Parallel Digital Output: Full-swing, no level shifting needed.
- Built-in Analog: on chip current reference and band gap that can be shared among multiple chips thanks to a dedicated pad.
- 2x2mm area,
- ESD protection at ADC input not limiting the > 1GHz input bandwidth
- Input clock can be AC or DC coupled
- Full power-down functionality of all blocks
