1 Rev.1.1 MINI ANALOG SERIES CMOS SINGLE COMPARATOR The mini-analog series mounts a general purpose analog circuit within a small package. The is a CMOS type single comparator that can be driven by lower voltage with lower consumption current than former bipolar comparator. This makes it the optimum solution for small battery powered portable equipment. Features Application CMOS single comparator Cellular phone Low operating voltage : V =1.8 to 5.5V Camera Low current consumption : I=50A (S-89210ACNC) PDA I=10A (S-89220ACNC) Notebook PC Low input offset voltage (4.0mV max) Digital camera Small package (SC-88A : mm2.1mm) Digital video camera Pin Configuration 5PIN SC-88A Top View V OUT IN(+) VSS IN(-) (S-89210ACNC S-89220ACNC) Pin No. Symbol Description Figure 1 1 IN(+) Noninverting input pin 2 VSS GND pin 3 IN(-) Inverting input pin 4 OUT Output pin 5 V Positive power supply pin Package SC-88A (PKG drawing code: NP005-B) Seiko Instruments Inc. 1

Power supply voltage rejection ratio, Offset voltage V Offset voltage(vio), Power supply voltage rejection ratio(svrr) - + VOUT The offset voltage (VIO) is defined as VIN when VOUT is changed by changing VIN to GND level. The power supply voltage rejection ratio (SVRR) can be calculated by value of VIO measured at each V and the following expression. VIN -V Figure 2 Measurement conditions : V1 is defined as V and VIO1 is defined as VIO when V is 0.9 V. V2 is defined V and VIO2 is defined as VIO when V is 2.5 V. VIO1 VIO2 SVRR 20log 2V 1 V2 2. Common-mode input signal rejection ratio, Common-mode input voltage - + V VIN1 VIN2 -V Figure 3 VOUT Common-mode input signal rejection ratio(cmrr) When the offset voltage (VIO) is set as VIN1 minus VIN2 after VOUT is changed by changing VIN1, the commonmode input signal rejection ratio (CMRR) can be calculated by the following expression. Measurement conditions : V = V VINH is defined as VIN2 and VIO1 is defined as VIO when VIN2 is 0.8 V. VINL is defined as VIN2 and VIO2 is defined as VIO when VIN2 is 0 V. CMRR 20log V INH V INL VIO1 VIO2 Common-mode input voltage(vcmr) Common-mode input voltage is a voltage in input voltage range that VOUT can be satisfied the Common-mode input voltage signal rejection ratio specification when VIN is changed. 6 Seiko Instruments Inc.
