MINI ANALOG SERIES
CMOS COMPARATOR S-89210A/89220A
Seiko Instruments Inc. 1
The mini-analog series is a group of ICs that incorporate a
general purpose analog circuit in a small package.
The S-89210A/89220A is a CMOS type comparator that has
a phase compensation circuit, and that can be driven at a
lower voltage with lower current consumption than existing
bipolar comparators. These features make this product the
ideal solution for small battery-powered portable equipment.
The S-89210A/89220A is a single comparator.
Features

Input offset voltage (VIO)
The input offset voltage (VIO) is defined as VIN − V
DD/2
when VOUT is changed by changing VIN to VDD/2 level.
The power supply voltage rejection ratio (PSRR) can be
calculated by following expression, with the value of VIO
measured at each VDD.
Measurement conditions:
When VDD = 1.8 V: VDD = VDD1, VIO = VIO1
When VDD = 5.0 V: VDD = VDD2, VIO = VIO2
PSRR = 20 log V

The common-mode input signal rejection ratio (CMRR)
can be calculated by the following expression, with the

changed by changing VIN1.
Measurement conditions:
When VIN2 = VCMR (max.): VIN2 = VINH, VIO = VIO1
When VIN2 = VDD/2: VIN2 = VINL, VIO = VIO2
