The LTC2657BIFE-L16#TRPBF is a Digital-to-Analog Converter (DAC) that is a member of the Data Acquisition (DAQ) family of integrated circuits. It is a precision, low-noise, 16-bit, voltage output DAC that offers 16 selectable output ranges from unity gain to 256x gain.

The DAC’s output is specified both in absolute and relative terms. Absolute accuracy is measured over the entire internal reference voltage and temperature range. Relative accuracy is measured at a single output voltage (VOUT) with respect to the reference voltage (VREF) over the specified temperature range. The differential nonlinearity (DNL) is typically +/– 1/2 LSB max, providing excellent monotonic performance.

The LTC2657BIFE-L16#TRPBF can accept multiple asynchronous write cycles to successive DAC registers, allowing adjustable slew rate for fast settling. An adjustable high-order attenuator and a precision overrange circuit provide the capability to boost gain to maximum full-scale ranges. An adjustable gain multiplexer rounds out the features.

The LTC2657BIFE-L16#TRPBF is ideal for applications that require high accuracy and fast settling times. The DAC offers an adjustable gain of up to 256 times that of its reference voltage. The settling time is largely dependent on the slew rate setting and the voltage change, both of which can be easily adjusted depending on the application. The overrange feature can also be used to boost the gain to maximum full-scale ranges.

The unit is available in a small, 4mm x 4mm, 24-pin TSSOP package, providing a wide range of applications. It is compatible with a variety of popular power supplies, making it an ideal choice for new designs. Moreover, its low-power consumption enables it to fit into battery-operated systems.

In operation, the LTC2657BIFE-L16#TRPBF takes in an analog voltage from a device, with VREF as the reference value, and converts it to a digital code word. This code word is then used to calculate the output voltage of the DAC, which is sent back to the device. The unit’s high-order attenuator and precision overrange circuit then boost the gain of the reference voltage to the desired output range.

The LTC2657BIFE-L16#TRPBF is a cost-effective and efficient solution for a variety of data acquisition applications. Its low-noise, 16-bit resolution and adjustable gain provide accurate and fast results, while its adjustable high-order attenuator and precision overrange circuit make boosting the gain to maximum full-scale ranges easy. Its small size and low power consumption make it suitable for portable systems, while its compatibility with a wide range of power supplies make it a popular choice for new designs. Overall, the LTC2657BIFE-L16#TRPBF is a versatile and reliable Digital-to-Analog Converter.
