Operation beyond the maximum operating conditions for extended periods may affect product reliability. The supply decoupling consists of a nF capacitor to ground. To select the gain resistor and the feedback resistor, refer to Figure 38 and Figure The AD can also be used as a single-ended-todifferential amplifier with similar distortion products as in the Rev.

Low Distortion Differential RF/IF Amplifier AD8351 Data Sheet

Throughout Changes to Features From Figure 38, select an RG for the required dB gain at a given load. Allows for monitoring or adjustment of the output common-mode voltage.

Fabricated in Analog Devices, Inc. The input and output impedances and reflection coefficients are provided in Figure 22, Figure 23, Figure 24, and Figure C4 through C7 are used to provide ac coupling. Voltage applied to this pin sets the common-mode voltage at both the input and output. Please enter samples into your cart to check sample availability. For detailed drawings and chemical composition please consult our Package Site.


Transit times from these sites may vary. BoxNorwood, MAU. T1 is a 1-to-1 impedance ratio balun used to transform a single-ended input into a balanced differential signal. The high impedance environment between the terminating resistors and device input pins must not have ground planes underneath or near the signal traces. By applying a voltage to Pin 3 of header P1, the output common-mode voltage can be directly adjusted.

Rarely Asked Questions 1. The quiescent current of the AD is 28 mA typically. D Page 14 of 19 Data Sheet AD Due to package parasitic capacitance on the RG ports, high RG values low gain cause high ac-peaking inside the pass band, resulting in poor settling in the time domain. The unused input is ac-coupled to ground. The Sample button will be displayed if a model is available for web samples. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

Many SAW filters daatasheet inherently differential, allowing for a low loss output match. Following the precautions outlined in Figure 45 helps to reduce parasitic board capacitance, thus extending the bandwidth of the device and reducing potential peaking or oscillation. Select the values of C1 through C4 such that their reactances are negligible at the desired frequency of operation. The evaluation board integrates datasbeet transformers to allow single ended or differential inputs and output, place holders for an impedance matching network and the evaluation board requires only a single supply within the range of 3.

One Technology Way, P.

The various ranges specified are as follows:. Resources AD Gerber Files.


C4 and C5 are used to provide ac coupling. Other models listed in the table may still be available if they have a status that is not obsolete. Gain Resistor Input 2. The specific part is obsolete and no longer available.

The voltage gain can be set from unity to 26 dB using a single external gain resistor. Do not connect to this pin. Used to trim common-mode output level. Even though the differential balance is not perfect under these conditions, the distortion performance is still impressive.

Pin Count Pin Count is the number of pins, balls, or pads on the device. By using an N-bit digital interface, up to N devices can be controlled. Typically decoupled to ground with a 0. RL is the single-ended load resistance. Due to environmental concerns, ADI offers many of our products in lead-free versions. Differential Circuit Representation Figure 33 illustrates the expected input and output waveforms for a typical application.
