1 DESCRIPTION Demonstration circuit 7A features the LTC 9 Dual Differential Amplifier/ADC Driver. It incorporates a variety of passive components to support configurations for varied applications. These fully-differential amplifiers accept single-ended or differential input with almost no difference in distortion performance. The LTC9 is a high speed dual differential amplifier with superior distortion and low noise, suitable for demanding communications transceivers, cellular base-stations and other high speed signal chain applications. ADDITIONAL INFORMATION The DC7A demo board is ready for use as-is and is designed for ease of use and with minimum modification. The demo board has features that can be accessed by adding, removing or changing components on the board to configure for single-ended and/or differential inputs and outputs. By default, the board is configured to have dual single-ended inputs with transformers, J (IN ) and J (IN ) and dual single-ended outputs with transformers, J (OUT ) and J7 (OUT ). Each of these ports is matched to 5Ω impedance to facilitate direct connections to test equipment. Driving the Inputs DC-Coupled It is possible to configure the DC7A inputs differentially with DC coupling. Transformers and components at locations T, T, C, C, C and C7 connections should be replaced with Ω resistors. The inputs are now DC-coupled and can be driven single-ended or differentially (resistor values may be changed to balance the source impedances). Changing the Output Common-Voltage The turrets marked VOCM and VOCM (E and E) control the output (and input, if AC-coupled) common mode voltage of the DC7A. This function can be used to level-shift the DC output voltage for optimum system performance. If used for this purpose, output capacitors DEMO MANUAL DC7A LTC9 Dual Differential Amplifier/ADC Driver C, C7, C and C8 can be replaced by Ω resistors to allow the DC bias to reach the outputs. By default, VOCMA and VOCMB are self-biased and float to a typical.5v on each of the common-mode pins (with V + = 5V). The VOCMA and VOCMB voltage of the two amplifiers can be set independently with external DC supply voltage source, or on board voltage dividers R8/ R9 and R7/R8. Enable (Shutdown) Jumpers JP and JP control the enable functions of amplifiers A and B. When set to the EN position, the part will be on and draw normal operating current. In the DIS position, the part will be in shutdown and draw a very small amount of leakage current. Ground and V CC Connections DC7A GND turret is not only connected to V of the LTC9, it also serves as the demo board s ground. For best result, a low impedance return path to the power supply from GND is recommended. Short, low impedance wires to the V + and GND connectors of DC7A will yield the best performance from the LTC9. Schematic Notes For a 5Ω external load, transformer T or T and the series Ω resistors (R7, R9 or R, R8) present each amplifier with a Ω load impedance. These resistors produce a db voltage drop when driving loads. Because the unmodified amplifier has db voltage gain, and each transformer adds approximately db insertion loss, the total unmodified demo board will measure approximately 8dB insertion loss from the input port (J or J) to the output port (J or J7).

2 DEMO MANUAL DC7A QUICK START PROCEDURE Table shows the function of each SMA connector on the board. Refer to Figure for the connection diagram and follow the procedure below:. Connect the power supply as shown. The power labels of V + and GND directly correspond to the power supply. Typical current consumption of LTC9 is about ma for both amplifiers. Jumpers JP and JP enable or shut down the amplifier A and amplifier B, respectively.. Apply input signal or network analyzer to J (IN ) or J (IN ). DC7A s input is impedance matched to 5Ω.. Observe the output via J (OUT ) or J7 (OUT ). The output is impedance matched to 5Ω, suitable for the input of a network or spectrum analyzer. Table shows the function of each input and output on the board. Table.
