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
interface to any analog input range between AGND and AVDD (0
to 2 V, 1 to 4 V, 0 to 5 V, etc.). The user simply sets VREF(+) and
VREF(–) to encompass the desired input range.
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
DB0 hold the current values and VREF(–) is disconnected from
VREF1(–). The power consumption during the power down mode
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.
