FEATURES
Easy Drive Greatly reduced input kickback Input current reduced to 0.5 μA/MSPS Enhanced acquisition phase, ≥77% of cycle time at 1 MSPS First conversion accurate, no latency or pipeline delay Input span pression for single-supply operation Fast conversion allows low SPI clock rates Input overvoltage clamp protection sinks up to 50 m A SPI-/QSPI-/MICROWIRE-/DSP-patible serial interface
High performance Differential analog input range: ±VREF, VREF from 2.4 V to 5.1 V Throughput: 1.8 MSPS/1 MSPS/500 k SPS options INL: ±3.1 ppm maximum Guaranteed 20-bit, no missing codes SNR: 100.5 d B at f IN = 1 k Hz, VREF = 5 V THD:
- 123 d B at f IN = 1 k Hz,
- 100 d B at f IN = 100 k Hz SINAD: 89 d B at f IN = 900 k Hz (see Figure 17) Oversampled dynamic range 104 d B for OSR = 2 131 d B for OSR = 1024
