Data Sheet
18-Bit, 2 MSPS/1 MSPS/500 kSPS, Precision, Pseudo Differential, SAR ADCs
AD4002/AD4006/AD4010
FEATURES
Easy Drive Greatly reduced input kickback Input current reduced to 0.5 μA/MSPS Enhanced acquisition phase, ≥79% of cycle time at 1 MSPS First conversion accurate, no latency or pipeline delay Input span compression for single-supply operation Fast conversion allows low SPI clock rates Input overvoltage clamp protection sinks up to 50 mA SPI-/QSPI-/MICROWIRE-/DSP-compatible serial interface
High performance Pseudo differential analog input range 0 V to VREF with VREF from 2.4 V to 5.1 V Throughput: 2 MSPS/1 MSPS/500 kSPS options INL: ±3.2 LSB maximum Guaranteed 18-bit, no missing codes SNR: 95 dB at fIN = 1 kHz at VREF = 5 V THD: −125 dB at fIN = 1 kHz, −108 dB at fIN = 100 kHz SINAD: 84.5 dB at fIN = 1 MHz (see Figure 17) Oversampled dynamic range 98 dB for OSR = 2 125 dB for OSR = 1024
Low power Single 1.8 V supply operation with 1.71 V to 5.5 V logic interface 2.5 mW at 500 kSPS (VDD only) 70 μW at 10 kSPS, 14 mW at 2 MSPS (total power)
