D/A converter provides six unique software-programmable output ranges

Milpitas, Calif.—Linear Technology Corp. has introduced the LTC2753-16, a dual 16-bit current output D/A converter 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. The LTC2753-16 offers accurate DC specifications, including ±1LSB (max) INL and DNL over the -40°C to +85°C industrial temperature range.

Operating from a single 2.7V to 5.5V supply, the LTC2753-16 draws a maximum supply current of 1-µA. The six unique SoftSpan output voltage ranges include two unipolar ranges (0V to 5V, 0V to 10V) and four bipolar ranges (±10V, ±5V, ±-2.5V, -2.5V to +7.5V). With its software programmability, low power and precision DC specifications, the LTC2753-16 is well-suited for ATE data acquisition modules such as PC/104.

The LTC2753-16's AC specifications include a full-scale settling time of 2µs and low 1nVs glitch impulse. The LTC2753-16's good AC specifications are key for applications such as waveform generation. Low glitch reduces the transient voltages between code changes in the D/A converter. 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.

Pricing: Begins at $5.95 each in 1,000-piece quantities.

Availability: Today in commercial and industrial temperature ranges.
