TSV630 - tsv631 application information 11/23 3 application information 3.1 operating voltages the TSV630 and tsv631 can operate from 1.5 to 5.5 v. their parameters are fully specified for 1.8-, 3.3- and 5-v power supplies. however, the parameters are very stable in the full v cc range and several characterization curves show the tsv63x characteristics at 1.5 v. additionally, the main specifications are guaranteed in extended temperature ranges from -40 c to +125 c. 3.2 rail-to-rail input the TSV630 and tsv631 are built with two complementary pmos and nmos input differential pairs. the devices have a rail-to-rail input, and the input common mode range is extended from v dd -0.1 v to v cc +0.1 v. the transition between the two pairs appears at v cc -0.7 v. in the transition region, the performance of cmrr, psrr, v io and thd is slightly degraded (as shown in figure 16 and figure 17 for v io vs. v icm ). the device is guaranteed without phase reversal. 3.3 rail-to-rail output the operational amplifiers? output levels can go close to the rails: 35 mv maximum above and below the rail when connected to a 10 k resistive load to v cc /2. figure 16. input offset voltage vs input common mode at v cc = 1.5 v figure 17. input offset voltage vs input common mode at v cc = 5 v -0.2 -0.2 0.0 0.0 0.2 0.2 0.4 0.4 0.6 0.6 0.8 0.8 1.0 1.0 1.2 1.2 1.4 1.4 1.6 1.6 -0.5 -0.5 -0.4 -0.4 -0.3 -0.3 -0.2 -0.2 -0.1 -0.1 0.0 0.0 0.1 0.1 0.2 0.2 0.3 0.3 0.4 0.4 0.5 0.5 input offset voltage (mv) input common mode voltage (v) 0.0 0.0 1.0 1.0 2.0 2.0 3.0 3.0 4.0 4.0 5.0 5.0 -0.4 -0.4 -0.2 -0.2 0.0 0.0 0.2 0.2 0.4 0.4 input offset voltage (mv) input common mode voltage (v)
application information TSV630 - tsv631 12/23 3.4 shutdown function (TSV630) the operational amplifier is enabled when the shdn pin is pulled high. to disable the amplifier, the shdn must be pulled down to v dd . when in shutdown mode, the amplifier output is in a high impedance state. the shdn pin must never be left floating, but tied to v cc or v dd . the turn-on and turn-off time are calculated for an output variation of 200 mv ( figure 18 and figure 19 show the test configurations). figure 18. test configuration for turn-on time (vout pulled down) figure 19. test configuration for turn-off time (vout pulled down) vcc-0.5v + - +vcc dut gnd 2ko gnd vcc-0.5v + - +vcc dut gnd 2ko gnd figure 20. turn-on time, v cc =5v, vout pulled down, t = 25 c figure 21. turn-off time, v cc =5v, vout pulled down, t = 25 c shutdown pulse vout vcc = 5v t = 25c voltage (v) time( s) shutdown pulse vout vcc = 5v t = 25c output voltage (v) time( s)
TSV630 - tsv631 application information 13/23 3.5 optimization of dc and ac parameters these devices use an innovative approach to reduce the spread of the main dc and ac parameters. an internal adjustment achieves a very narrow spread of the current consumption (60 a typical, min/max at 17 %). parameters linked to the current consumption value, such as gbp, sr and avd, benefit from this narrow dispersion. all parts present a similar speed and the same behavior in terms of stab ility. in addition, the minimum values of gbp and sr are guaranteed (gbp = 730 khz minimum and sr = 0.25 v/s minimum). 3.6 driving resistive and capacitive loads these products are micro-power, low-voltage operational amplifiers optimized to drive rather large resistive loads, above 2 k . for lower resistive loads, the thd level may significantly increase. in a follower configuration, these operational amplifiers can drive capacitive loads up to 100 pf with no oscillations. when driving lar ger capacitive loads, adding an in-series resistor at the output can improv e the stability of the devices (see figure 22 for recommended in-series resistor values). once the in-series resistor value has been selected, the stability of the circuit should be tested on bench and simulated with the simulation model. figure 22. in-series resistor vs. capacitive load 3.7 pcb layouts for correct operation, it is advised to add 10 nf decoupling capacitors as close as possible to the power supply pins. in-series resistor ()
