... MSOP packages. It has a rail-to-rail output buffer and is guaranteed monotonic. The LTC2637-L has a full-scale output of 2.5V, and operates from a single 2.7V to 5.5V supply. The LTC2637-H has a full-scale output of 4.096V, and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the DAC full-scale output to the external reference voltage ...

... The LTC2637 is a family of octal voltage output DACs in 14-lead DFN and 16-lead MSOP packages. Each DAC can operate rail-to-rail using an external reference, or with its full-scale voltage set by an integrated reference. Eighteen combinations of accuracy (12-, 10-, and 8-bit), power-on reset value (zero-scale, mid-scale in internal reference mode, or mid-scale in external reference mode), and full- scale voltage (2 ...

... The slave address assignments are shown in Tables 1 and 2. In addition to the address selected by the address pins, the part also responds to a global address. This address allows a common write to all LTC2637 parts to be ac- complished using one 3-byte write transaction on the bus ...

... The master initiates communication with the LTC2637 with a START condition and a 7-bit slave address followed by the Write bit ( The LTC2637 acknowledges by pulling the SDA pin low at the 9th clock if the 7-bit slave address matches the address of the part (set by CA0, CA1 or CA2) or the global address ...

Adding bypass capacitance to the REF pin will improve noise performance; and up to 10µF can be driven without oscillation. The REF output must be buffered when driving an external DC load current ...

... DACs will also power up the integrated reference. Voltage Output The LTC2637’s DAC output integrated rail-to-rail amplifiers have guaranteed load regulation when sourcing or sinking up to 10mA at 5V, and 5mA at 3V. Load regulation is a measure of the amplifier’s ability to maintain the rated voltage accuracy over a wide range of load current ...

... LTC2637 operation analog section of the ground plane. The resistance from the LTC2637 GND pin to the ground plane should be as low as possible. Resistance here will add directly to the effective DC output impedance of the device (typically 0.1Ω). Note that the LTC2637 is no more susceptible to this effect than any other parts of this type ...
