A high slew rate, rail-to-rail input and output capability, and low power consumption are the features which make the operational amplifier ideal for LCD applications. The RT9137/RT9138/RT9139 also has wide bandwidth and phase margin to drive a panel load. Operating Voltage The RT9137/8/9 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. The RT9137/8/9 specifications remain stable over the entire supply range and operating temperature range from −40°C to 85°C. Parameter variations with operating voltage and temperature are shown in the typical performance curves. The output swing of the RT9137/8/9 typically extends to within 80mV of positive/negative supply rails with 5mA load current source/sink. where TJ(MAX) is the maximum junction temperature, TA is the ambient temperature, and θJA is the junction to ambient thermal resistance. For recommended operating condition specifications of the RT9137/8/9, the maximum junction temperature is 125°C and TA is the ambient temperature. The junction to ambient thermal resistance, θJA, is layout dependent. The thermal resistance, θ JA, is 160°C/W for TSOT-23-5 package, 120°C/W for WDFN-6L 2x2 package, 120°C/W for MSOP-8 package, 50°C/W for TSSOP-14 (Exposed Pad) package, 120°C/W for TSSOP-14 package, 54°C/W for WQFN-16L 4x4 package, 120°C/W for MSOP-10 package, and 70°C/W for WDFN-10L 3x3 package, on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at TA = 25°C can be calculated by the following formulas : PD(MAX) = (125°C − 25°C) / (160°C/W) = 0.625W for TSOT-23-5 package PD(MAX) = (125°C − 25°C) / (120°C/W) = 0.833W for Short Circuit Condition WDFN-6L 2x2 package An internal short circuit protection circuit is implemented to protect the device from output short circuit. The RT9137/ 8/9 limits the short circuit current to ±300mA when supply voltage is ±7.5V. For reliability concerns, a continuous output current of not more than ±35mA is recommended. PD(MAX) = (125°C − 25°C) / (120°C/W) = 0.833W for Unused Amplifier If the amplifier is unused, it is recommended to connect the positive input to ground while keeping the output pin open. Thermal Considerations For continuous operation, do not exceed absolute maximum junction temperature. The maximum power dissipation depends on the thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. The maximum power dissipation can be calculated by the following formula : PD(MAX) = (TJ(MAX) − TA) / θJA www.richtek.com 12 MSOP-8 package PD(MAX) = (125°C − 25°C) / (50°C/W) = 2W for TSSOP-14 (Exposed Pad) package PD(MAX) = (125°C − 25°C) / (120°C/W) = 0.833W for TSSOP-14 package PD(MAX) = (125°C − 25°C) / (54°CW) = 1.852W for WQFN-16L 4x4 package PD(MAX) = (125°C − 25°C) / (120°C/W) = 0.833W for MSOP-10 package PD(MAX) = (125°C − 25°C) / (70°C/W) = 1.429W for WDFN-10L 3x3 package The maximum power dissipation depends on the operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA. For the RT9137/8/9 packages, the derating curves in Figure 1 allow the designer to see the effect of rising ambient temperature on the maximum power dissipation.

The following layout guidelines should be strictly followed for best performance of the RT9137/8/9. ` Place the components as close to the IC as possible. The traces should be wide and short, especially for the high current loop. ` Connect a 0.1μF capacitor from VIN+ to ground and place it as close to the IC as possible for better performance. ` A series resistance may be needed at the output for some applications. ` The exposed pad of the chip should be connected to a strong ground or VS- plane for maximum thermal consideration. 0.80 0.60 0.40 0.20 0.00 0 25 50 75 100 125 Ambient Temperature (°C) Figure 1.
