ADS1220IPW, 24-х разрядный АЦП 2KSPS 16-TSSOP

Описание ADS1220IPW The ADS1220IPW is a precision, 24-bit Analogue-to-digital Converter (ADC) IC, offers many integrated features to reduce system cost and component count in applications measuring small sensor signals. The device features two differential or four single-ended inputs through a flexible input multiplexer (MUX), a low-noise, programmable gain amplifier (PGA), two programmable excitation current sources, a voltage reference, an oscillator, a low-side switch and a precision temperature sensor. The device can perform conversions at data rates up to 2000 samples-per-second (SPS) with single-cycle settling. At 20 SPS, the digital filter offers simultaneous 50 and 60Hz rejection for noisy industrial applications. The device supports measurements of pseudo- or fully-differential signals when using the PGA. • Low Current Consumption • 1 to 128V/V Programmable Gain • Up to 2kSPS Programmable Data Rate • Up to 20-bit Effective Resolution • Simultaneous 50 and 60Hz Rejection at 20 SPS with Single-Cycle Settling Digital Filter • Two Differential or Four Single-ended Inputs • 10µA to 1.5mA Dual-matched Programmable Current Sources • 5ppm/°C (Typical) Drift Internal 2.048V Reference • Internal 2% Accurate Oscillator • 0.5°C (Typical) Accuracy Internal Temperature Sensor • SPI™-compatible Interface (Mode 1) • Green Product, No Sb/Br Архитектураацп сигма-дельта(sigma-delta)Разрешение (Бит)24Частота дискретизации (выб/сек.)2kКоличество A/D конвертеров1Количество входных каналов4Тип входадифференциальный, с общей землейИнтерфейс данныхspiНапряжение питания: аналоговое / цифровое2.3…5.5 в, ±2.5 в/2.3…5.5 вРабочая температура,°С-40…+125Корпусtssop-16 (0.173 inch)Вес, г0.4
