LTC2309CF#PBF - 8-Channel, 12-Bit SAR ADC with I2C Interface

The LTC2309CF#PBF is a high-performance, 8-channel, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Linear Technology, designed to provide precise digital representation of analog signals in a compact form factor. This versatile ADC is an ideal solution for a wide range of applications, including process control systems, data acquisition, medical equipment, and industrial automation.

Featuring an integrated I2C interface, the LTC2309CF#PBF allows for easy communication with most microcontrollers and digital systems, enabling efficient data transfer with minimal pin count. The device supports a fast I2C-compatible serial interface that can operate in both standard mode (100kHz) and fast mode (400kHz), providing flexibility in system design.

One of the key features of this ADC is its ability to handle eight single-ended input channels or four differential input pairs, giving designers the freedom to monitor multiple signals simultaneously. This flexibility makes it a versatile choice for systems that require multi-channel data acquisition without the need for additional external multiplexers.

The LTC2309CF#PBF operates from a single 5V supply and includes a reference buffer, a sample-and-hold circuit, and a high-speed SAR ADC. It delivers a high level of performance with a guaranteed 12-bit no missing codes resolution and offers a conversion rate of up to 50ksps, ensuring timely and accurate data conversion for real-time applications.

For enhanced precision, the device features a low noise performance and a wide input common-mode range, which includes ground. It also has a nap and sleep mode, allowing for power savings between conversions, which is particularly beneficial for battery-powered devices.

The LTC2309CF#PBF is offered in a compact 16-lead narrow SSOP package, making it suitable for space-constrained applications. Its robust design ensures reliable operation over the industrial temperature range of -40°C to +85°C. With its combination of features, the LTC2309CF#PBF is a powerful ADC option for engineers looking to improve the accuracy and efficiency of their analog-to-digital conversions.
