APPLICATIONS INFORMATION

POWER SUPPLY RAILS

To guarantee correct operation of the ADGS5412, 0.1 µF

decoupling capacitors are required.

The ADGS5412 can operate with bipolar supplies between ±9 V

and ±22 V. The supplies on VDD and VSS do not have to be

symmetrical; however, the VDD to VSS range must not exceed 44 V.

The ADGS5412 can also operate with single supplies between

9 V and 40 V with VSS connected to GND.

The voltage range that can be supplied to RESET/VL is from 2.7 V

to 5.5 V.

The device is fully specified at ±15 V, ±20 V, +12 V, and +36 V

analog supply voltage ranges.

POWER SUPPLY RECOMMENDATIONS

Analog Devices, Inc. has a wide range of power management

products to meet the requirements of most high performance

signal chains.

An example of a bipolar power solution is shown in Figure 47.

The ADP5070 (dual switching regulator) generates a positive and

negative supply rail for the ADGS5412, amplifier, and/or a

precision converter in a typical signal chain. Also shown in

Figure 47 are two optional LDOs, ADP7118 and ADP7182,

positive and negative low dropout regulators (LDOs), respectively,

that can be used to reduce the output ripple of the ADP5070 in

ultralow noise sensitive applications.

The ADM7160 can be used to generate the RESET/VL voltage

that is required to power digital circuitry within the ADGS5412.
