The NE/SE5018/19 is a complete 8-bit digital-to-analog converter subsystem with features such as input latches and low-loading data inputs.
The NE/SE5018/5019 is a complete 8-bit digital-to-analog converter (D/A) subsystem integrated onto a single monolithic chip. It features data inputs with ultra-low loading latches controlled by a latch enable pin, ensuring compatibility with various microprocessors such as the 8085 and 6800 series.
The device includes an on-chip stable voltage reference (nominal 5V) that can be externally trimmed for full-scale adjustment. It also incorporates a high slew rate buffer amplifier capable of both unipolar and bipolar output operation, with protection against short circuits for both the amplifier and the reference.
| Relative accuracy | +0.19% FS |
|---|---|
| Positive supply voltage (Voct) | -15V to 18V |
| Negative supply voltage (Voc-) | -18V to -11.4V |
| Logic '0' input voltage (Vin(0)) | 0.8V max |
| Logic '1' input current (Iin(1)) | 0.4 to 10 uA |
| Output short circuit current (Ios) | 15 to 40 mA |
| Settling time (+1/2LSB) | 1.8 us (low-to-high), 2.3 us (high-to-low) |
| Propagation delay (TE Low-to-high) | 300 ns |
The chip is compatible with the 8085, 6800 and many other uPs.
The device is available in 22-Pin Ceramic Dual In-Line Package (CERDIP), 22-Pin Plastic Dual In-Line Package (DIP), and 24-Pin Small Outline Large (SOL) Package.
The NE5018 operates in a temperature range of 0 to +70°C.
It is used for precision D/A converters, A/D converters, programmable power supplies, test equipment, measuring instruments, and analog-digital multiplication.
