To use at temperature above TA=25C reduce 5.5mW/C. Mounted on a FR4 glass epoxy PCB 70mm×70mm×1.6mm (Copper foil area less than 3%). The voltage difference between inverting input and non-inverting input is the differential input voltage. Then input pin voltage is set to more than VSS. (Note 5) An excessive input current will flow when input voltages of more than VDD+0.6V or less than VSS-0.6V are applied. The input current can be set to less than the rated current by adding a limiting resistor. Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. www.rohm.com © 2013 ROHM Co., Ltd.

Items and symbols used are also shown. Note that item name and symbol and their meaning may differ from those on another manufacturer’s document or general document. 1. Absolute Maximum Ratings Absolute maximum rating items indicate the condition which must not be exceeded. Application of voltage in excess of absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of characteristics. (1) Supply Voltage (VDD/VSS) Indicates the maximum voltage that can be applied between the VDD terminal and VSS terminal without deterioration or destruction of characteristics of internal circuit. (2) Differential Input Voltage (VID) Indicates the maximum voltage that can be applied between non-inverting and inverting terminals without damaging the IC. (3) Input Common-mode Voltage Range (VICM) Indicates the maximum voltage that can be applied to the non-inverting and inverting terminals without deterioration or destruction of electrical characteristics. Input common-mode voltage range of the maximum ratings does not assure normal operation of IC. For normal operation, use the IC within the input common-mode voltage range characteristics. (4) Power Dissipation (PD) Indicates the power that can be consumed by the IC when mounted on a specific board at the ambient temperature 25°C (normal temperature). As for package product, PD is determined by the temperature that can be permitted by the IC in the package (maximum junction temperature) and the thermal resistance of the package. 2. Electrical Characteristics (1) Input Offset Voltage (VIO) Indicates the voltage difference between non-inverting terminal and inverting terminals. It can be translated into the input voltage difference required for setting the output voltage at 0 V. (2) Input Offset Current (IIO) Indicates the difference of input bias current between the non-inverting and inverting terminals. (3) Input Bias Current (IB) Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias currents at the non-inverting and inverting terminals. (4) Supply Current (IDD) Indicates the current that flows within the IC under specified no-load conditions. (5) Maximum Output Voltage(High) / Maximum Output Voltage(Low) (VOH/VOL) Indicates the voltage range of the output under specified load condition. It is typically divided into maximum output voltage High and low. Maximum output voltage high indicates the upper limit of output voltage. Maximum output voltage low indicates the lower limit. (6) Large Signal Voltage Gain (AV) Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal and inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage. Av = (Output voltage) / (Differential Input voltage) (7) Input Common-mode Voltage Range (VICM) Indicates the input voltage range where IC normally operates. (8) Common-mode Rejection Ratio (CMRR) Indicates the ratio of fluctuation of input offset voltage when the input common mode voltage is changed. It is normally the fluctuation of DC. CMRR = (Change of Input common-mode voltage)/(Input offset fluctuation) (9) Power Supply Rejection Ratio (PSRR) Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. It is normally the fluctuation of DC. PSRR= (Change of power supply voltage)/(Input offset fluctuation) (10) Output Source Current/ Output Sink Current (ISOURCE / ISINK) The maximum current that can be output from the IC under specific output conditions. The output source current indicates the current flowing out from the IC, and the output sink current indicates the current flowing into the IC. (11) Output Fall Time (tF) Indicates the time required for an output voltage step to change from 90% to 10% of its final value. (12) Propagation Delay Time (L to H) / Propagation Delay Time (H to L) (tPLH / tPHL) Indicates the time to reach 50% of the output voltage after the step voltage is applied at the input pin. www.rohm.com © 2013 ROHM Co., Ltd.

As the IC consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and consumable power. Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold resin or lead frame of the package. Thermal resistance, represented by the symbol θJA°C/W, indicates this heat dissipation capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance. Figure 44(a) shows the model of the thermal resistance of the package. The equation below shows how to compute for the Thermal resistance (θJA), given the ambient temperature (TA), maximum junction temperature (TJmax), and power dissipation (PD). θJA = (TJmax-TA) / PD °C/W The Derating curve in Figure 44(b) indicates the power that the IC can consume with reference to ambient temperature. Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal resistance (θJA), which depends on the chip size, power consumption, package, ambient temperature, package condition, wind velocity, etc. This may also vary even when the same of package is used. Thermal reduction curve indicates a reference value measured at a specified condition. Figure 44(c) to (f) shows the derating curve for BU7250G, BU7250SG, BU7253F and BU7253SF.
