The LTC2485CDD#PBF is a multi-channel highly accurate analog to digital converter (ADC) with a powerful data acquisition system ideal for automotive and industrial applications. It has a broad selection of inputs and a capable selection of channels as each chip contains four 16-bit delta-sigma ADCs with each channel capable of sampling up to 10 million times per second (10 MHz).

The chip\'s input channels have a wide range of analog input levels, including single-ended inputs (0 V to 5 V), differential (± 5 V), and multi-gauge single-ended (0.56 V to 5 V). This gives it excellent compatibility with a variety of sensors from thermocouples to resistive bridge based transducers. The four channels of the chip are each independent of each other and operate with synchronized sampling rates. This allows for high precision data measurements to be taken even when switching between input channels.

The LTC2485CDD#PBF operates with a low power consumption as it uses an advanced logic design in order to reduce the power consumption of the chip. It also incorporates a patented translinear design which uses current sources instead of transistors, allowing the chip to operate with greater accuracy and stability while conserving power. The translinear design also has the advantage of allowing the chip to operate across a wide temperature range from -40°C to +125°C.

In order to reduce the noise generated by the analog input signal and reduce power consumption, the LTC2485CDD#PBF employs a proprietary signal conditioning algorithm called White Square. The chip is able to automatically perform signal conditioning for any type of input signal, allowing for a high level of signal accuracy without the need for external filters or anti-aliasing circuitry. It also features a proprietary low noise differential amplifier, a programmable gain amplifier, and a built-in temperature sensor.

The chip is factory programmed with a variety of registers that allow the user to configure the analog input parameters and the sampling frequency. The chip also provides a serial interface that allows the user to control the analog inputs and the sample rate. An onboard oscillator allows the user to program the chip to sample at a rate of up to 10 MHz.

The industrial and automotive applications of the LTC2485CDD#PBF make it an ideal choice for data acquisition systems. Its wide range of inputs, adjustable sampling frequencies, and low power consumption enable it to be used in a wide variety of applications. Furthermore, its signal-conditioning and low noise differential amplifiers make it highly accurate for a variety of applications, making it ideal for applications such as temperature sensing, environmental sensing, machine safety and control, and medical equipment.
