ts100 5 op amp demo board page 2 ts100 5 db r1 p 1 rtfds d escription the ts100 5 db evaluation board with sc70 packaging provides one configuration, namely an inverting configuration. the ts100 5 db - sot evaluation board with sot23 packaging provides two configurations for evaluating the ts100 5 operational amplifier in one single pcb board, namely a non - inverting configuration located on the left - hand side of the board and an inverting configuration located on 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 supply or v dd /2 for the inverting configuration and at v dd /4 for the non - inverting configuration. the ts100 5 demo board provides a dedicated power supply for the non - inverting circuit and a dedicated 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. in both the non - invert ing and the inverting configuration, the ac - coupling capacitor creates a high pass filter. the resulting cut - off frequency, f c , is given as: f c = 1 2 in the non - inverting circuit, = 5=1m and = 5=0.1f. in the inverting case, = 10=1m and c=c1=0.1f . in both cases, these component values generate a high - pass cut - off frequency of 1.6hz. default configuration s non - inverting configuration in the non - inverting configuration, the circuits transfer function is given by the following equation: i = 1 with =2m and =2m the circuit signal gain is 2 with a circuit bandwidth of 10 khz. this results in an overall circuit bandwidth range of 1.6hz to 10 khz. inverting configuration in an inverting configuration, the circuits transfer func tion is given by the following equation: i = - 6 10 in this case, 6=1m and 10=1m. his results in a signal gain of - 1 with a circuit bandwidth of 10 khz and an overall circuit bandwidth range of 1.6hz to 10 khz. quick start procedures required equipment ? ts1005 demo board ? dc p ower supply, single or dual output ? function generator ? 4 - channel oscilloscope ? wo 1m oscilloscope probes non - inverting c onfiguration in order to evaluate the ts100 5 operational amplifier in the non - inverting config uration, the following steps are to be performed: 1) before connecting the dc power supply to the demo board power test points, turn on the power supply and set the dc voltage to 5.5v and then turn it off. 2) set the function generator frequency to 500hz and o utput level with a v oh = 2.35v and a v ol = 2.15v. this sets the input signal swing to 200mv pp , centered at 2.25v. 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 v dd and the ground terminal to gnd .
