MCP4725 pdf datasheet

accuracy ΔΣ A/D converter with differential inputs and
up to 16 bits of resolution in a small SOT-23-6 package.
The on-board precision 2.048V reference voltage
enables an input range of ±2.048V differentially
(Δ voltage = 4.096V). The device uses a two-wire I2C
compatible serial interface and operates from a single
2.7V to 5.5V power supply.
The MCP3425 device performs conversion at rates of
15, 60, or 240 samples per second (SPS) depending
on the user controllable configuration bit settings using
the two-wire I2C serial interface. This device has an onboard
programmable gain amplifier (PGA). The user
can select the PGA gain of x1, x2, x4, or x8 before the
analog-to-digital conversion takes place. This allows
the MCP3425 device to convert a smaller input signal
with high resolution. The device has two conversion
modes: (a) Continuous mode and (b) One-Shot mode.
In One-Shot mode, the device enters a low current
standby mode automatically after one conversion. This
reduces current consumption greatly during idle periods.
The MCP3425 device can be used for various high
accuracy analog-to-digital data conversion applications
where design simplicity, low power, and small footprint
are major considerations.
