Manufacturer: Linear Technology Corporation

Overview: LTC2301/LTC2305 1-/2-Channel, 12-Bit ADCs with I2C patible Interface.

General Description

n 12-Bit Resolution n Low Power: 1.5mW at 1ksps, 35μW Sleep Mode n 14ksps Throughput Rate n Internal Reference n Low Noise: SNR = 73.5dB n Guaranteed No Missing Codes n Single 5V Supply n 2-wire I2C patible Serial Interface with 9 Addresses Plus One Global for Synchronization n Fast Conversion Time: 1.3μs n 1-Channel (LTC2301) and 2-Channel (LTC2305) Versions n Unipolar or Bipolar Input Ranges (Software Selectable) n Internal Conversion Clock n Guaranteed Operation from –40°C to 125°C (MSOP Package) n 12-Pin 4mm × 3mm DFN and 12-Pin MSOP Packages APPLICATIONS The LTC®2301/LTC2305 are low noise, low power, 1-/2-channel, 12-bit successive approximation ADCs with an I2C patible serial interface.

These ADCs include an internal reference and a fully differential sample-andhold circuit to reduce mon mode noise.

The LTC2301/ LTC2305 operate from an internal clock to achieve a fast 1.3μs conversion time.
