Mingjiada Supply ADI LTC2641 16-Bit Unbuffered Voltage Output Digital-To-Analog Converters

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of the [ADI] LTC2641 series of 16-bit, single-channel, unbuffered voltage-output digital-to-analogue converters (DACs). Thanks to their high resolution, low power consumption, compact package and flexible SPI interface, these devices are widely used in applications requiring high voltage setting accuracy, such as industrial control, precision instruments, automatic test equipment and data acquisition systems.

The LTC2641 is a classic 16-bit voltage-output DAC from ADI, housed in a compact MSOP-8 package and supporting a single-supply voltage range of 2.7V to 5.5V. Its output is an unbuffered voltage, with the output range determined by the external reference voltage VREF, typically ranging from 0V to VREF. As it does not incorporate an internal output buffer amplifier, the LTC2641 offers advantages in terms of power consumption, noise and settling time; however, in practical applications, it is recommended that a high-input-impedance precision operational amplifier be connected downstream as a buffer to enhance drive capability and ensure linearity.

Key Features:
Compact 3mm × 3mm 8-pin DFN package
Maximum 16-bit INL error: ±1 LSB over the entire temperature range
Low supply current: 120μA
Monotonicity guaranteed over the entire temperature range
Low glitch current of 0.5nV • sec
Single-supply operation from 2.7V to 5.5V
Fast settling time of 1 μs to 16 bits
Unbuffered voltage output directly drives 60 k loads
50 MHz SPI / QSPI / MICROWIRE-compatible serial interface
Power-on reset clears the DAC output to zero scale (LTC2641) or mid-scale (LTC2642)
Schmitt-trigger inputs with direct optocoupler interface
Asynchronous CLR pin

The high precision and compact size of the LTC2641 make it widely used in a number of applications:
Industrial process control and PLC analogue outputs
Precision instruments and calibration equipment
Automated test equipment (ATE)
Data acquisition systems (DAQ)
Programmable voltage and current sources
Gain and bias adjustment circuits
Medical electronics and communications equipment
Portable, low-power measurement terminals
