DESCRIPTION
The ADS5411 is an 11 bit, 105 MSPS analog-to-digital converter (ADC) that operates from a 5 V supply, while providing
3.3 V CMOS compatible digital outputs. The ADS5411 input buffer isolates the internal switching of the on-chip Track and
Hold (T&H) from disturbing the signal source. An internal reference generator is also provided to further simplify the system
design. The ADS5411 has outstanding low noise and linearity, over input frequency. With only a 2.2 VPP input range,
simplifies the design of multicarrier applications, where the carriers are selected on the digital domain.
The ADS5411 is available in a 52 pin HTQFP with heatsink package. The ADS5411 is built on state of the art Texas
Instruments complementary bipolar process (BiCom3) and is specified over full industrial temperature range (−40°C to
85°C).
