DESCRIPTION
1-/2-Channel, 12-Bit ADCs
with I2C Compatible Interface
The LTC2301/LTC2305 are low noise, low power,
1-/2-channel, 12-bit successive approximation ADCs
with an I2C compatible serial interface. These ADCs include
an internal reference and a fully differential sample-and-
hold circuit to reduce common mode noise. The LTC2301/
LTC2305 operate from an internal clock to achieve a fast
1.3μs conversion time.
The LTC2301/LTC2305 operate from a single 5V supply
and draw just 300μA at a throughput rate of 1ksps. The
ADC enters nap mode when not converting, reducing the
power dissipation.
The LTC2301/LTC2305 are available in small 12-pin
4mm × 3mm DFN and 12-pin MSOP packages. The in-
ternal 2.5V reference further reduces PCB board space
requirements.
The low power consumption and small size make the
LTC2301/LTC2305 ideal for battery operated and portable
applications, while the 2-wire I2C compatible serial interface
makes these ADCs a good match for space-constrained
systems.
