TS1005 Demo Board REVISION NOTE FEATURES The current revision for the TS1005 Demo Boards 0.8V to 5.5V Single-supply operation display the identifier TS100x Demo Board on the AC-coupled Non-Inverting and Inverting top side of the evaluation board as depicted in configuration supplied Figure 1. If the identifier is not printed on the top Fully Assembled and Tested side of the evaluation board, please contact Silicon 2in x 2in 2-layer demo board Labs for support at: TS1005 Demo Board Description Inverting configuration The TS1005 evaluation boards provide two In an inverting configuration, the circuits transfer configurations for evaluating the TS1005 operational function is given by the following equation: amplifier in one single PCB board, namely a non- V R6 inverting configuration located on the left-hand side of OUT = - the board and an inverting configuration located on V R10 IN the right-hand side of the board. In both cases, the input to each circuit is AC-coupled. The demo board provides a re-biasing scheme at one-half the power In this case, R6=1M and R10=1M . This results in supply or VDD/2 for the inverting configuration and at V /4 for the non-inverting configuration. a signal gain of -1 with a circuit bandwidth of 10kHz DD and an overall circuit bandwidth range of 1.6Hz to The TS1005 demo board provides a dedicated power 10kHz. supply for the non-inverting circuit and a dedicated power supply for the inverting circuit. This provides Quick Start Procedures the user the flexibility of evaluating one circuit at a time or both at the same time. Required Equipment In both the non-inverting and the inverting TS1005 demo board configuration, the AC-coupling capacitor creates a high pass filter. The resulting cut-off frequency, f , is C DC Power Supply, Single or Dual Output given as: Function Generator 1 f = C 4-channel Oscilloscope 2RC Two 1M oscilloscope probes In the non-inverting circuit, R=R5=1M and C=C5=0.1F. In the inverting case, R=R10=1M and C=C1=0.1F. In both cases, these component values generate a high-pass cut-off frequency of 1.6Hz. Non-Inverting Configuration In order to evaluate the TS1005 operational amplifier Default Configurations in the non-inverting configuration, the following steps are to be performed: Non-Inverting configuration 1) Before connecting the DC power supply to the In the non-inverting configuration, the circuits transfer demo board power test points, turn on the power function is given by the following equation: supply and set the DC voltage to 5.5V and then turn it off. V R4 OUT = 1+ V R3 IN 2) Set the function generator frequency to 500Hz and output level with a VOH = 2.35V and a VOL = With R4=2M and R3=2M the circuit signal gain is 2.15V. This sets the input signal swing to 2 with a circuit bandwidth of 10kHz. This results in an 200mVPP, centered at 2.25V. overall circuit bandwidth range of 1.6Hz to 10kHz. 3) In order to monitor the input and output signal, select two channels on the oscilloscope and set the vertical voltage scale and the vertical position on each channel to 100mV/DIV and -2.25V, respectively. Set the horizontal time scale to 500s/DIV. 4) Connect the positive terminal of the DC power supply to VDD and the ground terminal to GND. Page 2 TS1005-EVB Rev. 1.0
