LJTick-Dac - Digital to Analog Converter
LJTick-DAC is an analog output expansion module that provides a pair of 14-bit analog outputs with a range of ±10 V.
Provides a pair of 14-bit digital to analog outputs with a range of ±10 V. Plugs into any digital I/O block, and thus up to 10 of these can be used per U3/U6/UE9/T4/T7 to add a total of 20 analog outputs.
The update rate is limited by the communication time between the host and the device. Generally it takes ≈1 ms to do an update via USB "high-high" or via Ethernet. While it takes ≈4 ms via other USB connections. Only 1 DAC channel can be updated per low-level communication.
Supply voltage: 4.5 to 5.5 V
Supply current:
- 5mA (Vout = 0, No load)
- 29mA - Both outputs at 3mA
DIO:
- Pull-up resistors: 5100Ω (to Vs)
- Low level input voltage: 0.3 x Vs Volt
- High level input voltage: 0.7 x Vs Volt
- Low level output voltage: 0 to 0.4 V (Sink current = 3mA)
- Clock frequency (DIOA): 400 kHz
DAC Outputs:
- Typical output range: -10.3 to 10.4 V
- Power-up output voltage: 0.05V
- Resolution: 14 bits
- Accuracy: 0.05 %F.S
- Differential linearity error: ±1 counts
- Integral linearity error: ±5 to ±16 counts
- Temperature drift: 20ppm/°C
- Update time: 1 ms
- Update rate: 1000 Hz
- Slew rate: 0.1 V/μs
- Output impedance: 0.1 Ω
- Output current: 10 mA (Total for both channels)
Operating temperature: 0 to 70°C
