PRODUCTION DATA
The THS4541 provides a very good low power option to drive the ADC inputs. Table 9-3
provides an overview of the THS4541 with power consumption and usable frequency.
| DEVICE | CURRENT (IQ) PER CHANNEL | USABLE FREQUENCY RANGE |
|---|---|---|
| THS4541 | 10 mA | < 70 MHz |
The low pass filter design (topology, filter order) is driven by the application itself. However, when designing the low pass filter, the optimum load impedance for the amplifier should be taken into consideration as well. Between the low pass filter and the ADC input the sampling glitch filter needs to added as well as shown in Section 8.3.1.2.1. In this example the DC - 30 MHz glitch filter is selected.
