Analog Devices Inc. LTC2657CUFD-H12#PBF - 16-Bit Digital-to-Analog Converters

The LTC2657CUFD-H12#PBF is a family of 16-bit, octal digital-to-analog converters (DACs) from Analog Devices Inc., designed to deliver precision and performance in a compact package. This product offers an ideal solution for demanding applications that require accurate analog output from digital signals. The LTC2657 is part of a series that provides various resolution options, but the H12 variant signifies a 16-bit resolution, ensuring high precision for the most sensitive applications.

Enclosed in a 28-lead QFN (4mm × 5mm) package, the LTC2657CUFD-H12#PBF features integrated output buffers and a reference with low drift, which ensures stability and low noise performance. This DAC operates from a single 2.7V to 5.5V supply and offers a full-scale output range that is programmable to either 0V to 5V, 0V to 10V, ±5V, or ±10V, providing flexibility for various application needs.

One of the key features of the LTC2657CUFD-H12#PBF is its robust interface which includes a SPI/Microwire compatible 3-wire serial interface that operates at clock rates up to 50MHz, making it suitable for high-speed, high-precision applications. This interface is designed to minimize the amount of digital I/O lines necessary to communicate with the device, which simplifies the board layout and reduces the overall system complexity.

Additionally, this product includes a power-on reset circuit that ensures the DAC output powers up to zero-scale or mid-scale and remains there until a valid write takes place. It also has a clear input that can asynchronously clear the DAC to zero-scale or mid-scale. The LTC2657CUFD-H12#PBF provides guaranteed monotonic performance over the entire operating temperature range and has a built-in thermal shutdown feature to protect the device under extreme conditions.

Applications for the LTC2657CUFD-H12#PBF are diverse and include industrial automation, process control, data acquisition systems, and digital gain and offset adjustment. With its combination of high precision, ease of use, and flexible output ranges, this product from Analog Devices Inc. is engineered to meet the rigorous demands of advanced digital-to-analog conversion requirements.
