Manufacturer:ALT Description:The EP1K30TI144-2N/EP1K30TI144-2N low-power, 3.5- and 4.5-digit, analog-to-digital converters (ADCs) with integrated liquid crystal display (LCD) drivers operate from a single 2.7V to 5.25V power supply. They include an internal refer- ence, a high-accuracy on-chip oscillator, and a triplexed LCD driver. An internal charge pump generates the neg- ative supply needed to power the integrated input buffer for single-supply operation. The ADC is configurable for either a 2V or 200mV input range and outputs its con- version results to an LCD and/or to a microcontroller (µC). µC communication is facilitated through an SPI™-/QSPI™-/MICROWIRE™-compatible serial inter- face. The EP1K30TI144-2N is a 3.5-digit (1999 count) device, and the EP1K30TI144-2N is a 4.5-digit (19,999 count) device. The EP1K30TI144-2N/EP1K30TI144-2N do not require external-preci- sion integrating capacitors, autozero capacitors, crystal 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 dif- ferential signal and reference inputs, allowing direct interface with high-impedance signal sources. In addi- tion, they use continuous internal-offset calibration and offer >100dB simultaneous rejection of 50Hz and 60Hz line noise. Other features include data hold and peak hold, overrange and underrange detection, and a low- battery monitor. The EP1K30TI144-2N comes in a 32-pin, 7mm x 7mm TQFP package, and the EP1K30TI144-2N comes in 28-pin SSOP and 28-pin PDIP packages. All devices in this family operate over the 0C to +70C commercial temperature range. |
