10MHz, Rail-to-Rail I/O CMOS Operational Amplifier
Features
Low Offset Voltage: 1mV (typ)
High Gain: 105dB (typ)
High Gain Bandwidth Product: 10MHz
Rail-to-rail Input/Output
Low I
B
: 5pA (typ)
Low supply voltage: +2.5 V to +5.5 V
Low Power Consumption: 1.2mA at 5 V
(per amplifier)
Extended Temperature: -40°C to +125°C
Product Description
The TS2177A/TS2178A families of products are low
noise, low voltage and low power operational
amplifiers with high gain-bandwidth product of 10MHz
and slew rate of 10V/μs. The maximum input offset
voltage is only 5mV and the input common mode
range extends beyond the supply rails.
TS2177A/TS2178A families of operational amplifiers
are specified at the full temperature range of
−40C to
+125C
under single or dual power supplies of 2.7V to
5.5V, however these products will operate under an
extended supply range from 2.5V to 5.5V at a
reduced temperatures range.
The TS2177A and TS2178A have a power-down
feature that reduces the supply current to 1uA.

ESD CAUTION
ESD (electrostatic discharge) sensitive device
Charged devices and circuit boards can
discharge without detection. Although this
product features patented or proprietary
protection circuitry, damage may occur on
devices subjects to high energy ESD. Therefore,
proper ESD precautions should be taken to
avoid performance degradation or loss of
functionality.
