MINI ANALOG SERIES
CMOS COMPARATOR
S-89210A/89220A
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
y Lower operating voltage than the conventional general-purpose
comparators:
VDD = 1.8 to 5.5 V
y Low current consumption: IDD = 50 µA (S-89210A)
IDD = 10 µA (S-89220A)
y Low input offset voltage:
4.0 mV (max.)
y Lead-free products
Application
y Cellular phones
y PDAs
y Notebook PCs
y Digital cameras

VOUT
The input offset voltage (VIO) is defined as VIN − VDD/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

The common-mode input signal rejection ratio (CMRR)
can be calculated by the following expression, with the
offset voltage (VIO) set as VIN1 minus VIN2 after VOUT is
changed by changing VIN1.

Measurement conditions:
When VIN2 = VCMR (max.): VIN2 = VINH, VIO = VIO1
