MAX1495CCJ+T 数据手册

3.5- and 4.5-Digit, Single-Chip

ADCs with LCD Drivers

General Description

Features

The MAX1491/MAX1493/MAX1495 low-power, 3.5- and

4.5-digit, analog-to-digital converters (ADCs) with inte-

grated liquid crystal display (LCD) drivers operate from a

single 2.7V to 5.25V power supply. They include an inter-

nal reference, a high-accuracy on-chip oscillator, and a

triplexed LCD driver. An internal charge pump generates

the negative supply needed to power the integrated input

buffer for single supply operation. The ADC is config-

urable for either a ±2V or ±2±±mV input range and it out-

puts its conversion results to an LCD. The MAX1491 is a

3.5-digit (±1,999 count) device, and the MAX1493/

MAX1495 are 4.5-digit (±19,999 count) devices.

ꢀ Operate from a Single 2.7V or 5.25V Supply

ꢀ Selectable Input Range of 200mV or 2V

The MAX1491/MAX1493/MAX1495 do not require exter-

nal-precision integrating or auto-zero capacitors, crys-

tal oscillators, charge pumps or other circuitry required

with dual slope ADCs (commonly used in panel meter

circuits). These devices also feature on-chip buffers for

the differential signal and reference inputs, allowing

direct interface with high-impedance signal sources. In

addition, the MAX1491/MAX1493/MAX1495 use contin-

uous internal offset calibration, and offer >1±±dB rejec-

tion of 5±Hz and 6±Hz line noise. The MAX1493/

MAX1495 perform enhanced offset calibration at

power-up. The MAX1495 also performs enhanced cali-

bration on demand. Other features include data hold

and peak hold, and a user programmable low-battery

monitor.

SSOP and 28-pin DIP packages. All devices in this fam-

ily operate over the ±°C to +7±°C commercial tempera-

ture range.
