RT9136 9 ds9136-03 june 2011 www.richtek.com figure 2. v-com test circuit applications information the RT9136 packaged in quad operational amplifiers has high performance to drive large load for different application. high slew rates, rail-to-rail input and output capability and low power consumption are the features to make the RT9136 ideal for lcd applications. the RT9136 also has wide bandwidth and phase margin to drive a load of 10k and 10pf. operating voltage the RT9136 is specified with a single nominal supply voltage from 5v to 15v or a split supply with its total range from 5v to 15v. correct operation is guaranteed for a supply range of 4.5v to 16.5v. RT9136 specifications are stable over both the full supply range and operating temperatures of ? 40 c to 85 c . parameter variations with operating voltage and/or temperature are shown in the typical performance curves. the output swing of the RT9136 typically extends to within 80mv of positive/negative supply rails with 5ma load current source/sink. decreasing the load current will get output swing even closer to the supply rails. figure 1 shows the rail-to-rail input and output waveforms in the unit gain configuration without load current. the supply rails are 5v. applying an input 10vp_p sinusoidal waveform results in a 9.8vp_p output voltage as shown in figure 1. short circuit condition an internal short-circuit protection circuit is implemented to protect the device from output short circuit. the RT9136 limits the short circuit current to 120ma if the output is directly shorted to positive/negative supply rails. for reliability, the continuous output current more than 35ma is not recommended. unused amplifier if the amplifier is unused. it is recommended to connect the positive input to ground and keep the output pin as open. figure 1. operation with rail-to-rail input and output lcd panel applications the RT9136 is mainly designed for lcd gamma and v-com buffer. op amplifier-c has 120ma instantaneous source/sink peak current. to test the performance of the RT9136 for lcd driving capability, the test circuit is to simulate the v-com driver as shown figure 2. series capacitors and resistors connected to the output of the op simulate the load of lcd panel. the 300 and 3k feedback resistors are used to improve the settling time. this circuit is the worst case for a v-com buffer. figure 3 shows the waveforms of the output peak current capability. time (250 s/div) input voltage (5v/div) output voltage (5v/div) + - 3k 300 v in 0v to 8v 10 10 10 10 10 8v 4v output current test point square wave 10nf 10nf 10nf 10nf
