TMS-SCE-3-16-2.0-3 TMS-SCE-3-16-2.0-3 TMSSCE316203 Datasheet Life support - These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury. Philips Semiconductors customers using or selling these products for use in such applications do so at their own risk and agree to fully indemnify Philips Semiconductors for any damages resulting from such application. TMS-SCE-3-16-2.0-3 TMS-SCE-3-16-2.0-3 TMSSCE316203 Price If AIN2 is desired (Figure 5b), drive CNVST high for at least 30ns. Next, drive it low for at least 30ns, and then high again. This will power-up the ADC and place the T/H in track mode with AIN2 connected to the positive input capacitor. Now hold CNVST high for tACQ to fully acquire the signal. Drive CNVST low to place the T/H in hold mode. The ADC will then perform a conversion and shutdown automatically. The MSB is available at TMS-SCE-3-16-2.0-3 TMS-SCE-3-16-2.0-3 TMSSCE316203 on stock PRODUCT OVERVIEW The AD1838 is a high performance single-chip codec featuring three stereo DACs and one stereo ADC. Each DAC comprises a high performance digitalinterpolation filter, a multibit sigma-delta modulator featuring Analog Devices' patented technology, (continued on Page 11) The output DC offset control pin can be used for sideband suppression in differential modulators, calibration of A/D conve rters, or simple signal summation. Since the voltage summing occurs at the output of the filter, Pin 5 acts as a unfiltered input. The response from Pin 5 to Pin 8 - Pin 7 with Pins l,2 and 3 grounded is shown in Figure 7. The range of voltages that can be applied to Pin 5 is shown in Figure 6 where THD is plotted versus output offset. Pin 3 is biased to mid supply. |
