MAX6078A集成電路（IC）的電壓基準規(guī)格書PDF中文資料

MAX6078A屬于集成電路（IC）的電壓基準。由亞德諾半導體技術有限公司制造生產的MAX6078A電壓基準產品屬于基準電壓源系列，可通過相對較不穩(wěn)定的電源提供穩(wěn)定的電勢，電壓值始終保持恒定，以便在測量、控制和類似應用中用作比較的標準。其功能行為可能與用于大功率調節(jié)的線性穩(wěn)壓器相似，但基準電壓源器件卻不適合用于此類用途。用作比較標準時，若輸出電流容量或實際負載電流增大，其性能通常會降低。

General Description

The MAX6078 precision voltage reference family provides

low drift and low noise at a maximum power supply current

of only 15μA. Low-frequency noise is less than 12μVP-P

(2.5V output voltage option) and the temperature coefficient

of the output voltage is less than 10ppm/°C.

The reference output can sink and source up to 3mA of

load current and the top grade provides an initial accuracy

of 0.04. The low-drift and low-noise specifications

enable enhanced system accuracy, making these devices

ideal for high-precision industrial applications. A noise reduction

(NR) input pin allows connection of an external capacitor

to reduce wideband noise. Available output voltages

include 1.25V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V,

and 5.0V.

The tiny, 6-bump WLP and small, 8-pin TDFN-EP packages

are suitable for systems where circuit board area is

limited. The operating input voltage can range from 2.3V

to 5.5V. Operation is specified over the extended industrial

temperature range of -55°C to +125°C.
