Dual DAC offers six different outputs
Software programmability eliminates the need for expensive precision resistors, gain stages and switching jumpers by hand.
Linear Technology has introduced the LTC2753-16, a dual 16bit current output DAC capable of outputting six unique software-programmable SoftSpan unipolar and bipolar output ranges up to +/-10V Software programmability eliminates the need for expensive precision resistors, gain stages and switching jumpers by hand

Card power chip meets smart and SIM standards
The LTC4557 is a dual SIM/smart-card power supply and level translator, which provides both 1.8 and 3V SIM power and digital signal level shifting from a 3 x 3mm QFN package.
RF mixers take transformers onboard
Linear Technology has released two new high linearity up-converting RF active mixers with integrated RF transformers.
The LTC2753-16 offers accurate DC specifications, including +/-1LSB maximum INL and DNL over the -40 to +85C industrial temperature range.
Operating from a single 2.7 to 5.5V supply, this DAC draws a maximum supply current of only 1uA.
The six unique SoftSpan output voltage ranges include two unipolar ranges (0 to 5 and 0 to 10V) and four bipolar ranges (+/-10, +/-5, +/-2.5 and -2.5 to +7.5V).
With its software programmability, low power and precision DC specifications, the LTC2753-16 is ideal for ATE data acquisition modules such as PC/104.
The LTC2753-16 also offers very good AC specifications, including full-scale settling time of only 2us and low 1nVs glitch impulse.
The LTC2753-16's good AC specifications are ideal for applications such as waveform generation.
Low glitch reduces the transient voltages between code changes in the DAC.
Fast settling and low glitch reduce the harmonic distortion, making it possible to produce higher frequency, lower noise output waveforms.
The LTC2753-16 uses a bidirectional input/output parallel interface that allows readback of any internal register, as well as the DAC output span setting.
The LTC2753-14 and LTC2753-12 are pin-compatible 14 and 12bit devices, respectively.
The LTC2753-16, LTC2753-14 and LTC2753-12 are all available in 7 x 7mm QFN-48 packages, offering a pin-compatible and code-compatible family for performance/cost optimisation in the end product.
For applications only requiring a single DAC, please refer to the LTC2751 16/14/12bit DAC family.
Both the dual LTC2753 and single LTC2751 DAC families are available today in commercial and industrial temperature ranges.
Pricing begins at US $5.95 each for the LTC2753-12, in 1000-piece quantities. Request a free brochure from Linear Technology Corp ...
