description
The TL507 is a low-cost single-slope analog-to-
digital converter designed to convert analog
inputvoltages between 0.25 V
CC1
and 0.75 V
CC1
into a pulse-width-modulated output code. The
device contains a 7-bit synchronous counter, a
binary weighted resistor ladder network, an
operational amplifier, two comparators, a buffer
amplifier, an internal regulator, and necessary
logic circuitry. Integrated-injection logic (I
2
L)
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.

FUNCTION TABLE
A high level on RESET clears the counter to zero,
which sets the internal ramp to 0.75 VCC. Internal
pulldown resistors keep RESET and ENABLE low
when not connected.
