ADC driver settles to 16 bits in 350 ns

Suitable for driving the latest highest-performance SAR ADCs, the LTC6350 rail-to-rail input and output ADC driver settles to 16 bits in just 350 ns. Each of the two internal op amps achieves a 1.9-nV/√Hz input-referred noise density, resulting in a total output-referred noise of just 8.2 nV/√Hz. The part enables high-performance ADCs to achieve better than 110-dB SNR over a 1-MHz bandwidth.

The part operates on 2.7 to 12-V total supply and consumes 4.8 mA supply current. Fully specified over the 0° to 70°C, 40° to 85°C, and –40° to 125°C temperature range, the part is available in 8-lead MSOP and 3 x 3-mm DFN packages. No external gain resistors are required. (From $2.59 ea/1,000 — available now.)
