These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. 71.5 MAX124_C Input Voltage Range 0VREF V Input Capacitance Aperture Jitter <50 ps 16 pF MAX124_A MAX124_B/C Aperture Delay tAPR 30 ns Figure 8 Track/Hold Acquisition Time tACQ 1.5 µs Throughput Rate 73 ksps fSCLK = 2.1MHz Conversion Time PARAMETER SYMBOL MIN TYP MAX UNITS ±0.5 ±3.0 Offset Error LSB Differential Nonlinearity DNL ±1 LSB ±1.0 Gain Temperature Coefficient ±0.5 ±4.0 Gain Error (Note 3) LSB ±0.5 ±4.0 Resolution 12 Bits Relative Accuracy (Note 2) INL ±0.5 LSB tCONV 5.5 7.5 µs Small-Signal Bandwidth Signal-to-Noise Plus Distortion Ratio SINAD 70 dB 2.25 MHz Full-Power Bandwidth Total Harmonic Distortion THD -80 dB 1.0 -3dB rolloff MHz CONDITIONS Spurious-Free Dynamic Range ppm/°C No missing codes over temperature MAX124_B/C ±0.25 SFDR MAX124_A/B 80 Up to the 5th harmonic dB MAX124_A/B MAX124_A MAX124_A/B MAX124_C -88 MAX124_C 88 ANALOG INPUT CONVERSION RATE DYNAMIC SPECIFICATIONS (10kHz sine-wave input, 0V to 2.500Vp-p, 73ksps, fSCLK = 2.1MHz) DC ACCURACY (Note 1) |
