3 / 8 page SP973T8 3 ELECTRICAL CHARACTERISTICS DEFINITIONS Analog Bandwidth The analog input frequency at which the spectral power of the fundamental frequency, as determined by Fast Fourier Transform analysis is 3dB down on the DC level. Aperture Delay The delay between the falling edge of the CLOCK signal and the instant at which the analog input is sampled. Bit Error Rate (BER) The number of spurious code errors produced for any given input sinewave frequency. In this case it is the number of codes occuring outside the histogram cusp for a 3/ 4 F.S. sinewave. Differential Non-Linearity (DNL) The deviation of any code width from an ideal 1LSB step. Effective Number of Bits (ENOB) This is a measure of the dynamic performance and is calculated from the following expression. ENOB = SNR-1.76 6.02 SNR is the signal-to-noise ratio, in decibels, at the test frequency. Integral Non-Linearity (INL) The deviation of the centre of each code from a reference line which has been determined by a least squares curve fit. Output Data Delay The delay between the 50% point of the falling edge of the clock signal and the 50% point of any data output change. Reference Ladder Offset The voltage error at the ends of the resistor chain caused by the lead frame and bond wire. Signal-to-Noise Ratio (SNR) The ratio of the RMS signal amplitude to the RMS value of 'noise' which is defined as the sum of all other spectral components including harmonics but excluding DC with a full scale analog input signal. Test Levels Level 1 - 100% production tested Level 2 - 100% production tested at 25°C and sample tested at specified temperatures Level 3 - Sample tested only Level 4 - Parameter is guaranteed by design and characteristics testing Level 5 - Parameter is a typical value only Description Output data bits 3, 2, 1, 0 Clock input pin Clock threshold level pin Bottom of reference resistor chain Function D3, D2, D1, D0 CLK CLK VRB AVCC AGND VRM VIN VRT DVCC DGND D7 D6, D5, D4 Pin No. 1, 2, 3, 4 5 6 7 8 9 10 11 12 13 14 15 16, 17, 18 5 Volt power to all circuitry except the TTL output Middle of reference resistor chain Analog input voltage pin Top of reference resistor chain 5 Volt power supply to the TTL output stage Most significant bit (output data bit 7) Output data bits 6, 5, 4 THERMAL CHARACTERISTICS DP Thermal resistance, chip-to-case θjc 20 °C/W Thermal resistance, chip-to-ambient θjA 75 °C/W RECOMMENDED OPERATING CONDITIONS Supply Voltage VCC +5.0V Reference VRT +4.3V Reference VRB +2.3V AVCC to DVCC 0mV AGND to DGND 0mV Analog Input VIN 2 Vp-p max PIN DESCRIPTIONS |
