The LTC2630CSC6-LM12#TRMPBF is a 16-bit Serial Input, Voltage Output Digital-to-Analog Converter (DAC) of Data Acquisition – Digital to Analog Converters (DAC). It offers an unrivaled mix of performance, package size and price tag. This part operates from an 2.2V to 5.25V supply, and provides output voltage from 0V to VREF (referenced to V SS).

The LTC2630CSC6-LM12#TRMPBF is organized as one R-2R ladder per channel with a voltage reference, current steering DAC and output buffer. Consisting of two eight-bit DACs internally connected in series, the series output is then converted to a voltage output.The hard-wire configuration of the LTC2630CSC6-LM12#TRMPBF allows two user selectizable modes: a full-scale output (VREF) of 2.048V or 4.096V and an output current range of 2mA or 4mA. The voltage output range is customer programmable via four independent 10-bit DACs.

LTC2630CSC6-LM12#TRMPBF is used for various applications such as industrial process control and test & measurement. It can easily be interfaced to any system with a serial port such as a microprocessor, microcontroller and DSP. The device includes a 3-wire SPI/MICROWIRE compatible serial interface and supports standard SPI, QSPI and MICROWIRE™ protocol.

In addition, LTC2630CSC6-LM12#TRMPBF includes an internal voltage reference and is equipped with ten LDAC inputs, which will allow the user to write multiple DAC registers simultaneously. The device also features a power-on reset circuit that is used to reset all DAC registers to zero-scale. This part is provided with a variety of protection features like thermal shutdown, reverse current protection and open-drain control.

The LTC2630CSC6-LM12#TRMPBF is built-in with a Shutdown/Reset pin that allows to reduce current consumption by placing the device in shutdown mode. A logic high-level on this pin will reset all DACs registers to zero-scale. This allows the user to easily reconfigure the DAC without having to cycle the power. In addition, this part is provided with an internal fault detection circuit which will detect any output, input and internal voltage reference errors.

Other features of the LTC2630CSC6-LM12#TRMPBF include an on-chip 62 Ω precision output resistor, a precision zero-scale module, and an internal power-on reset circuit. The combination of these features makes the LTC2630CSC6-LM12#TRMPBF the ideal choice for applications that require the highest resolution and lowest noise. This device is available in a tiny 6-pin TDFN package, which makes it suitable for space-constrained applications.
