11 / 16 page AD9070 –11– REV. B +5 V Operation The AD9070 may be operated above ground, with a single +5 V power supply. All power supply ground pins are connected to +5 V, and VEE pins are connected to ground (Figure 22). Care must be taken in connecting signals and determining bypass rails. The reference voltage (REF OUT) is still generated with respect to the positive rail, which is now +5 V. It is nominally +2.5 V, but its voltage with respect to ground will vary directly with changes in the power supply voltage (for example, if the power supply goes to +5.1 V, the reference becomes +2.6 V). The reference input is likewise processed with respect to +5 V. This dictates that these pins be bypassed to +5 V as well. However, the COMP and REF BYPASS pins must continue to be bypassed to the most negative supply, which is now ground. The AIN input must still be connected or bypassed to the ground reference of the input signal.

AD9070 in +5 V (PECL) Environment Package Options The AD9070 is available in two packages. The BR package is a standard 28-lead Small Outline IC (SOIC). The DIP package is a ceramic Dual-in-Line Hybrid. The SOIC is offered in a commer- cial grade, and specified over the industrial (–40 °C to +85°C) temperature range. The DIP is a full MIL-PRF-38534 QML version that operates from (–55 °C to +125°C). The SOIC version includes the on-chip voltage reference, whereas the DIP does not. The DIP, however, provides the Overrange (OR) output, and includes reference and power supply bypassing, along with an internal compensation capacitor. Equivalent performance may be obtained with either part though, due to the internal bypassing, the DIP is not as sensitive to board layout and parasitics. |
