General Description
The DAC0808 is an 8-bit monolithic digital-to-analog converter (DAC) featuring a full scale output current settling time of 150 ns while dissipating only 33 mW with ±5V supplies.
No reference current (IREF) trimming is required for most applications since the full scale output current is typically ±1 LSB of 255 IREF/256. Relative accuracies of better than ±0.19% assure 8-bit monotonicity and linearity while zero level output current of less than 4 µA provides 8-bit zero accuracy for IREF³2 mA. The power supply currents of the DAC0808 is independent of bit codes, and exhibits essentially constant device characteristics over the entire supply voltage range.

 The DAC0808 will interface directly with popular TTL, DTL or CMOS logic levels, and is a direct replacement for the MC1508/MC1408. For higher speed applications, see DAC0800 data sheet.

Features
* Relative accuracy: ±0.19% error maximum
* Full scale current match: ±1 LSB typ
* Fast settling time: 150 ns typ
* Noninverting digital inputs are TTL and CMOS compatible
* High speed multiplying input slew rate: 8 mA/µs
* Power supply voltage range: ±4.5V to ±18V
* Low power consumption: 33 mW @ ±5V

General Description
The DAC0800 series are monolithic 8-bit high-speed current-output digital-to-analog converters (DAC) featuring typical settling times of 100 ns. When used as a multiplying DAC, monotonic performance over a 40 to 1 reference current range is possible. The DAC0800 series also features high compliance complementary current outputs to allow differential output voltages of 20 Vp-p with simple resistor loads.
 The reference-to-full-scale current matching of better than ±1 LSB eliminates the need for full-scale trims in most applications, while the nonlinearities of better than ±0.1% over temperature minimizes system error accumulations.
 The noise immune inputs will accept a variety of logic levels. The performance and characteristics of the device are essentially unchanged over the ±4.5V to ±18V power supply
range and power consumption at only 33 mW with ±5V supplies is independent of logic input levels.
 The DAC0800, DAC0802, DAC0800C and DAC0802C are a direct replacement for the DAC-08, DAC-08A, DAC-08C, and DAC-08H, respectively. For single supply operation, refer to AN-1525.

General Description
 The ADC14V155 is a high-performance CMOS analog-todigital converter with LVDS outputs. It is capable of converting analog input signals into 14-Bit digital words at rates up to 155 Mega Samples Per Second (MSPS). Data leaves the chip in a DDR (Dual Data rate) format; this allows both edges of the output clock to be utilized while achieving a smaller package size.  
 
 This converter uses a differential, pipelined architecture with digital error correction and an on-chip sample-and-hold circuit to minimize power consumption and the external component count, while providing excellent dynamic performance. A unique sample-and-hold stage yields a full-power bandwidth of 1.1 GHz. The ADC14V155 operates from dual +3.3V and +1.8V power supplies and consumes 951 mW of power at 155 MSPS.
 
 The separate +1.8V supply for the digital output interface allows lower power operation with reduced noise. A powerdown feature reduces the power consumption to 15 mW while still allowing fast wake-up time to full operation. In addition there is a sleep feature which consumes 50 mW of power and has a faster wake-up time.

 The differential inputs provide a full scale differential input swing equal to 2 times the reference voltage. A stable 1.0V internal voltage reference is provided, or the ADC14V155 can be operated with an external reference. Clock mode (differential versus single-ended) and output data format (offset binary versus 2's complement) are pin-selectable.
 A duty cycle stabilizer maintains performance over a wide range of input clock duty cycles. It is available in a 48-lead LLP package and operates over the industrial temperature range of −40°C to +85°C.

General Description
The LM1237 pre-amp is an integrated CMOS CRT preamp. It has an I2C compatible interface which allows control of all the parameters necessary to directly setup and adjust the gain and contrast in the CRT display. Brightness and bias can be controlled through the DAC outputs which are well matched to the LM2479 and LM2480 integrated bias clamp ICs. The LM1237 preamp is also designed to be compatible with the LM246x high gain driver family.
Black level clamping of the video signal is carried out directly on the AC coupled input signal into the high impedance preamplifier input, thus eliminating the need for additional clamp capacitors. Horizontal and vertical blanking of the outputs is provided. Vertical blanking is optional and its duration is register programmable. The IC is packaged in an industry standard 24 lead DIP molded plastic package.
