超摆幅、低导通漏电流模拟开关
概述
优势和特性
MAX14760/MAX14762/MAX14764模拟开关允许通过超出
其电源电压摆幅的双极性信号,器件采用+3.0V至+5.5V电
源供电,支持-25V至+25V的信号范围。
S简化电源需求
 3.0V至5.5V供电范围
 -25V至+25V信号范围
MAX14760为单通道单刀单掷(SPST)模拟开关,MAX14762
为双路SPST模拟开关,MAX14764则为单通道单刀双掷
(SPDT)模拟开关。
S高性能
 ±10nA (最大值)导通漏电流(MAX14760/MAX14762)
 20Ω (最大值)导通电阻
 低至58mΩ (典型值)的导通电阻平坦度
 热关断保护
 -40℃至+85℃工作温度范围
 宽带:115MHz (典型值)
MAX14760/MAX14762/MAX14764具有20Ω (最大值)导通电
阻和±10nA (最大值)导通漏电流(MAX14760/MAX14762)。
MAX14760/MAX14764提供8引脚(3mm x 3mm) TDFN封装,
MAX14762提供10引脚(3mm x 3mm) TDFN封装。这些器件
能够工作在-40℃至+85℃扩展级温度范围。
S节省电路板空间
 小尺寸、8引脚和10引脚TDFN封装

详细说明
应用信息
MAX14760/MAX14762/MAX14764模拟开关能够处理超摆
幅信号。器件采用+3.0V至+5.5V单电源供电,可处理-25V
至+25V范围的信号。
上电条件
VCC上电1秒内确保A_、B_或COM输入端没有负信号。
模拟信号范围
器件能够切换-25V至+25V范围的超摆幅信号,在-25V至
+25V整个输入电压范围内,器件导通电阻保持较高的平坦
度(58mΩ)。模拟开关允许通过双向电流,所以A、A1、A2、
B、B1、B2和COM既可作为输入,也可作为输出。
旁路电容
VP和VN引脚需要接外部电容,以稳定偏置。建议采用1μF
陶瓷电容,确保可靠工作。不要将VP和VN用作其它电路的
供电电源。

MAX14760/MAX14762/MAX14764
Above- and Below-the-Rails
Low-Leakage Analog Switches
General Description
Benefits and Features
The MAX14760/MAX14762/MAX14764 analog switches
are capable of passing bipolar signals that are beyond
their supply rails. These devices operate from a single
+3.0V to +5.5V supply, and support signals in the -25V
to +25V range.
S Simplify Power-Supply Requirements
3.0V to 5.5V Supply Range
-25V to +25V Signal Range
S High Performance
Q10nA (max) On-Leakage Current (MAX14760/
MAX14762)
20I (max) On-Resistance
Low On-Resistance Flatness, 58mI (typ)
Thermal Shutdown Protection
-40NC to +85NC Operating Temperature Range
High Bandwidth:115MHz (typ)
The MAX14760 is a single-pole/single-throw (SPST) analog switch, while the MAX14762 is a dual-SPST analog
switch. The MAX14764 is a single-pole/double-throw
(SPDT) analog switch.
The MAX14760/MAX14762/MAX14764 feature 20I (max)
on-resistance with a Q10nA (max) on-leakage current for
MAX14760/MAX14762.
S Save Space on Board
Small 8-Pin and 10-Pin TDFN Packages
The MAX14760/MAX14764 are available in 8-pin (3mm x
3mm) TDFN packages. The MAX14762 is available in a
10-pin (3mm x 3mm) TDFN package. These devices are
specified over the -40NC to +85NC extended operating
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.

Detailed Description
Applications Information
The MAX14760/MAX14762/MAX14764 analog switches
are capable of handling signals above and below their
rails. These devices operate from a single +3.0V to +5.5V
supply and support signals in the -25V to +25V range.
Ensure that negative signals are not present on the A_,
B_, or COM inputs before 1 second has passed after
applying VCC.
Power-Up Conditions
Analog Signal Range
The devices switch signals in the range from -25V to
+25V that are above and below their rails. The on-resistance for these devices exhibits a high degree of flatness
(58mI) over the whole input voltage range of -25V to
+25V. The analog switches allow bidirectional current
flow, so A, A1, A2, B, B1, B2, and COM, can be used as
either inputs or outputs.
Bypass Capacitors
Bias-stabilizing capacitors are required on the VP and VN
pins. 1FF ceramic capacitors are suggested for effective
operation. VP and VN are not intended as a power supply
for other circuitry.
