T he AD773A is a monolithic 10-bit, 20 Msps analog-to-digital

converter incorporating an on-board, high performance track-

and-hold amplifier (T HA). T he AD773A converts video

bandwidth signals without the use of an external T HA. T he

AD773A implements a multistage differential pipelined

architecture with output error correction logic. T he AD773A

offers accurate performance and guarantees no missing codes

over the full operating temperature range.

1. On-board T HA

T he high impedance differential input T HA eliminates the

need for external buffering or sample and hold amplifiers.

T he T HA offers the choice of differential or single-ended

inputs. Input current is typically 5 µA.

2. High Impedance Reference Input

T he high impedance reference input (200 kΩ) allows direct

connection with standard +2.5 V references, such as the

AD680, AD580 and REF43.

Output data is presented in binary and twos complement

format. An out of range (OT R) signal indicates the analog input

voltage is beyond the specified input range. OT R can be

decoded with the MSB/MSB pins to signal an underflow or

overflow condition. T he high impedance reference input allows

multiple AD773As to be driven in parallel from a single

reference.

3. Output Data Flexibility

Output data is available in bipolar offset and bipolar twos

complement binary format.

4. Out of Range (OT R)

T he OT R output bit indicates when the input signal is

beyond the AD773A’s input range.

T he combined dc precision and dynamic performance of the

AD773A is useful in a variety of applications. T ypical

applications include: video enhancement, HDT V, ghost

cancellation, ultrasound imaging, radar and high speed data

acquisition.

5. Military T emperature Range

T he AD773A was designed using Analog Devices’ ABCMOS-1

process which utilizes high speed bipolar and 2-micron CMOS

transistors on a single chip. High speed, precision analog

circuits are now combined with high density logic circuits. Laser

trimmed thin film resistors are used to optimize accuracy and

temperature stability.

T he AD773A is packaged in a 28-pin ceramic DIP and is

available in commercial (0°C to +70°C) and military (–55°C to

+125°C) grades.
