TS1003 Demo Board REVISION NOTE FEATURES The current revisions for the TS1003 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: TS1003 Demo Board Description Inverting configuration The TS1003 evaluation boards provide two In an inverting configuration, the circuits transfer configurations for evaluating the TS1003 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 a signal gain of -1 with a circuit bandwidth of 2kHz supply or VDD/2 for the inverting configuration and at V /4 for the non-inverting configuration. and an overall circuit bandwidth range of 1.6Hz to DD 2kHz. The TS1003 demo board provides a dedicated power supply for the non-inverting circuit and a dedicated Quick Start Procedures power supply for the inverting circuit. This provides the user the flexibility of evaluating one circuit at a time or both at the same time. Required Equipment TS1003 demo board In both the non-inverting and the inverting configuration, the AC-coupling capacitor creates a DC Power Supply, Single or Dual Output high pass filter. The resulting cut-off frequency, f , is C Function Generator given as: 4-channel Oscilloscope 1 f = C 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 Non-Inverting Configuration generate a high-pass cut-off frequency of 1.6Hz. In order to evaluate the TS1003 operational amplifier in the non-inverting configuration, the following steps Default Configurations are to be performed: 1) Before connecting the DC power supply to the Non-Inverting configuration demo board power test points, turn on the power In the non-inverting configuration, the circuits transfer supply and set the DC voltage to 5.5V and then function is given by the following equation: turn it off. V R4 OUT 2) Set the function generator frequency to 500Hz = 1+ V R3 IN = 2.35V and a V = and output level with a VOH OL 2.15V. This sets the input signal swing to With R4=2M and R3=2M the circuit signal gain is 200mV , centered at 2.25V. PP 2 with a circuit bandwidth of 2kHz. This results in an overall circuit bandwidth range of 1.6Hz to 2kHz. 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 and the ground terminal to GND. supply to VDD TS1003-EVB Rev. 1.0 Page 2
