6-Bit A/D converter (parallel outputs)
Product specification
NE5037
DESCRIPTION
The NE5037 is a low cost, complete successive-approximation
analog-to-digital (A/D) converter, fabricated using Bipolar/I2L
technology. With an external reference voltage, the NE5037 will
accept input voltages between 0V and VREF. An external START
pulse of at least 300ns in duration will provide the 6-bit result of the
conversion in parallel format. Full conversion with no missing codes
occurs in 9µs.
FEATURES
• TTL-compatible inputs and outputs
• 3-State output buffer
• Easy interface to CMOS microprocessors
• Fast conversion—9µs
• Guaranteed no missing codes over full temp range
• Single-supply operation, +5V
• Positive true binary outputs
• High-impedance analog inputs
APPLICATIONS
• Temperature control
