ANALOG DEVICES模塊AD7714YNZ產(chǎn)品介紹
AD7714 是一款完整的模擬前端，適用于低頻測量應(yīng)用。該器件直接從傳感器接收低電平信號并輸出串行數(shù)字字。它采用 sigma-delta 轉(zhuǎn)換技術(shù)，可實(shí)現(xiàn)高達(dá) 24 位的無失碼性能。輸入信號應(yīng)用于基于模擬調(diào)制器的專有可編程增益前端。調(diào)制器輸出由片上數(shù)字濾波器處理。該數(shù)字濾波器的第一個陷波可通過片上控制寄存器進(jìn)行編程，從而允許調(diào)整濾波器截止和穩(wěn)定時間。
該器件具有三個差分模擬輸入（也可配置為五個偽差分模擬輸入）以及一個差分參考輸入。因此，AD7714 可為包含多達(dá)五個通道的系統(tǒng)執(zhí)行所有信號調(diào)節(jié)和轉(zhuǎn)換。最近，現(xiàn)有系列中又添加了一個新 Y 級。與 A 級相比，這個新級具有更大的工作溫度范圍、SCLK 和 DIN 上的施密特觸發(fā)器輸入、更嚴(yán)格的線性度規(guī)格、更低的功耗，并且采用更小的封裝。
AD7714 非常適合用于基于智能微控制器或 DSP 的系統(tǒng)。它具有一個串行接口，可以配置為三線操作。可以使用串行端口在軟件中配置增益設(shè)置、信號極性和通道選擇。AD7714 提供自校準(zhǔn)、系統(tǒng)校準(zhǔn)和后臺校準(zhǔn)選項(xiàng)，還允許用戶讀取和寫入片上校準(zhǔn)寄存器。
CMOS 結(jié)構(gòu)確保非常低的功耗，斷電模式可將待機(jī)功耗降低至 3 V 時的典型值 15 μW。A 級的最低工作電壓為 3 V，Y 級的最低工作電壓為 2.7 V。A 級采用 24 引腳、0.3 英寸寬的塑料雙列直插式封裝 (DIP)；24 引腳小外形 (SOIC) 封裝和 28 引腳縮小外形封裝 (SSOP)。新的 Y 級產(chǎn)品采用 24 引腳、0.3 英寸寬的塑料雙列直插式封裝 (DIP)；24 引線小外形 (SOIC) 封裝和 24 引線薄型縮小外形封裝 (TSSOP)。

The AD7714 is a complete analog front end for low-frequency measurement applications. The device accepts low level signals directly from a transducer and outputs a serial digital word. It employs a sigma-delta conversion technique to realize up to 24 bits of no missing codes performance. The input signal is applied to a proprietary programmable gain front end based around an analog modulator. The modulator output is processed by an on-chip digital filter. The first notch of this digital filter can be programmed via the on-chip control register allowing adjustment of the filter cutoff and settling time.
The part features three differential analog inputs (which can also be configured as five pseudo-differential analog inputs) as well as a differential reference input. The AD7714 thus performs all signal conditioning and conversion for a system consisting of up to five channels. A new Y grade has recently been added to the existing range. Compared to the A grades this new grade has an extended operating temperature range, schmitt trigger inputs on SCLK and DIN, tighter linearity specifications, lower power consumption and is available in a smaller package.
The AD7714 is ideal for use in smart microcontroller- or DSP-based systems. It features a serial interface that can be configured for three-wire operation. Gain settings, signal polarity and channel selection can be configured in software using the serial port. The AD7714 provides self-calibration, system calibration and background calibration options and also allows the user to read and write the on-chip calibration registers.
CMOS construction ensures very low power dissipation, and the power-down mode reduces the standby power consumption to 15 μW typical at 3 V. Minimum operating voltage for the A grades is 3 V and 2.7 V for the Y grades. The A grades are available in a 24-pin, 0.3 inch-wide, plastic dual-in-line package (DIP); a 24 lead small outline (SOIC) package and a 28-lead shrink small outline package (SSOP). The new Y grade is available in a 24-pin, 0.3 inch-wide, plastic dual-in-line package (DIP); a 24 lead small outline (SOIC) package and a 24-lead Thin Shrink Small Outline Package (TSSOP).
