GENERAL DESCRIPTION

The MP8798 is a flexible, easy to use, precision 10-bit

Analog-to-Digital Converter with 4-channel mux that operates

over a wide range of input and sampling conditions.

The

MP8798 can operate with pulsed “on demand” conversion

operation or continuous “pipeline” operation for sampling rates

up to 1 MHz. The elimination of the S/H, requirements, very low

power, and small package size offer the designer a low cost

solution. No sample and hold is required for charge couple

device applications, up to 1 MHz, or multiplexed input

applications when the signal source bandwidth is limited to 100

kHz.

The input

architecture of the MP8798 allows direct

Scaled reference resistor tap 1/2 R allows for customizing

the transfer curve as well as providing a 1/2 span reference

voltage. Digital outputs are CMOS and TTL compatible.

The MP8798 uses a two-step flash technique.

The first

segment converts the 4 MSBs and consists of 15 autobalanced

comparators, latches, an encoder, and buffer storage registers.

The second segment converts the remaining 6 LSBs.

When the power down input is “high”, the data outputs DB9 to

is approximately 3mW.

Specified for operation over the commercial / industrial (–40

to +85

°C) temperature range, the MP8798 is available in plastic

dual-in-line (PDIP), surface mount (SOIC), and shrink small

outline (SSOP) packages.
