The TL507 is a low-cost single-slope analog-todigital converter designed to convert analog inputvoltages between 0.25 VCC1 and 0.75 VCC1 into a pulse-width-modulated output code. The device contains a 7-bit synchronous counter, abinary weighted resistor ladder network, an operational amplifier, two comparators, a buffer amplifier, an internal regulator, and necessary logic circuitry. Integrated-injection logic (I2L) technology makes it possible to offer this complex circuit at low cost in a small dual-in-line 8-pin package.
In continuous operation, conversion speeds of up to 1000 conversions per second are possible. The TL507 requires external signals for CLK, RESET, and ENABLE. Versatility and simplicity of operation, coupled with low cost, makes this converter especially useful for a wide variety of applications.
The TL507C is characterized for operation from 0°C to 70°C, and the TL507I is characterized for operation from 40°C to 85°C.
