LTC2201 16-Bit, 20Msps ADC FEATURESDESCRIPTION n Sample Rate: 20Msps The LTC®2201 is a 20Msps, sampling 16-bit A/D converter n 81.6dB SNR and 100dB SFDR (2.5V Range) designed for digitizing high frequen cy, wide dynamic range n 90dB SFDR at 70MHz (1.667VP-P Input Range) signals with input frequencies up to 380MHz. The input n PGA Front End (2.5VP-P or 1.667VP-P Input Range) range of the ADC can be optimized with the PGA front end. n 380MHz Full Power Bandwidth S/H The LTC2201 is perfect for demanding app lications, with n Optional Internal Dither AC performance that includes 81.6dB SNR and 100dB n Optional Data Output Randomizer spurious free dynamic range (SFDR). Maximum DC specs n Single 3.3V Supply include ±5LSB INL, ±1LSB DNL (no missing codes). n Power Dissipation: 211mW n Clock Duty Cycle Stabilizer A separate output power supply allows the CMOS output n Out-of-Range Indicator swing to range from 0.5V to 3.6V. n Pin Compatible Family A single-ended CLK input controls converter operation. An 25Msps: LTC2203 (16-Bit) optional clock duty cycle stabilizer allows high performance 10Msps: LTC2202 (16-Bit) at full speed with a wide range of clock duty cycles. n 48-Pin (7mm × 7mm) QFN Package L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
