GENERAL DESCRIPTION

BUSY

DGND

The AD7575 is a high speed 8-bit ADC with a built-in track/

hold function. The successive approximation conversion tech-

nique is used to achieve a fast conversion time of 5 µs, while the

built-in track/hold allows full-scale signals up to 50 kHz (386 mV/µs

slew rate) to be digitized. The AD7575 requires only a single +5 V

supply and a low cost, 1.23 V bandgap reference in order to convert

PRODUCT HIGHLIGHTS

1. Fast Conversion Time/Low Power

The fast, 5 µs, conversion time of the AD7575 makes it

suitable for digitizing wideband signals at audio and ultra-

sonic frequencies while retaining the advantage of low

CMOS power consumption.

an input signal range of 0 to 2 V_REF

The AD7575 is designed for easy interfacing to all popular 8-bit

microprocessors using standard microprocessor control signals

(CS and RD) to control starting of the conversion and reading of

the data. The interface logic allows the AD7575 to be easily

configured as a memory mapped device, and the part can be

interfaced as SLOW-MEMORY or ROM. All data outputs of

the AD7575 are latched and three-state buffered to allow direct

connection to a microprocessor data bus or I/O port.

2. On-Chip Track/Hold

The on-chip track/hold function is completely self-contained

and requires no external hold capacitor. Signals with slew

rates up to 386 mV/µs (e.g., 2.46 V peak-to-peak 50 kHz sine

waves) can be digitized with full accuracy.

3. Low Total Unadjusted Error

The zero, full-scale and linearity errors of the AD7575 are so

low that the total unadjusted error at any point on the trans-

fer function is less than 1 LSB, and offset and gain adjust-

ments are not required.

The AD7575 is fabricated in an advanced, all ion-implanted high

speed Linear Compatible CMOS (LC²MOS) process and is

available in a small, 0.3" wide, 18-lead DIP, 18-lead SOIC or in

other 20-terminal surface mount packages.

4. Single Supply Operation

Operation from a single +5 V supply with a low cost +1.23 V

bandgap reference allows the AD7575 to be used in 5 V

microprocessor systems without any additional power

supplies.

5. Fast Digital Interface

Fast interface timing allows the AD7575 to interface easily to

the fast versions of most popular microprocessors such as the

Z80H, 8085A-2, 6502B, 68B09 and the DSP processor, the

TMS32010.
