MAX394 低電圧、クワッド、SPDT CMOSアナログスイッチ - Maxim

19-0391; Rev 0; 5/95
低電圧、クワッド、SPDT
CMOSアナログスイッチ
特長 _______________________________
MAX394は、高精度、低電圧クワッド単極双投(SPDT)
アナログスイッチです。4個の独立したスイッチは、
±2.7V∼±8Vのデュアル電源あるいは+2.7V∼+15Vの
単一電源で動作します。MAX394は低オン抵抗
(35Ω以下)、
2Ω以下のチャネル間マッチング、及び全アナログ信号
範囲でΔ4Ω以下の平坦性を保証しています。また、
ブレーク・ビフォ・メークのスイッチング(10ns typ)
機能を備え、ターンオフ時間は75ns以下、ターンオン
時間は130ns以下です。MAX394は全入力がハイ又は
ローのときの自己消費電流が1µA以下と低いため、ポー
タブル機器に最適です。
◆ 低オン抵抗:17Ωtyp (35Ω max)
このモノリシック、クワッドスイッチは、マキシム社
の低電圧シリコンゲートプロセスで製造されています。
設計の改良により、超低チャージインジェクション
(10pC)、低消費電力(10µW)、及び2000V以上の静電放電
(ESD)耐性が保証されています。
◆ TTL/CMOSロジックコンパチブル
ロジック入力はTTL及びCMOSコンパチブルで、+8Vま
での電源電圧では+0.8V∼+2.4Vの範囲が保証されていま
す。また電源電圧が+8Vを超える場合、入力は+0.8V∼
+4V(typ)です。ロジック入力及びスイッチングされる
アナログ信号は、素子にダメージを与えることなく、
電源電圧範囲まで可能です。

Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to
maximum current rating.
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.

The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Guaranteed by design.
∆RON = ∆RON(max) - ∆RON(min). On-resistance match between channels and flatness are guaranteed only with
specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as
measured over the specified analog signal range.
Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature.
See Figure 6. Off isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch.
Between any two switches. See Figure 3.
Leakage testing at single supply is guaranteed by testing with dual supplies.

アプリケーション情報 _________________
±5V以外の電源電圧での動作
MAX394スイッチは、±2.7V∼±8Vのデュアル電源及び
+2.7V∼+15Vの単一電源で動作します。どちらの場合に
も、V+∼V-の範囲のアナログ信号のスイッチングが可
能です。アナログ信号及び電源電圧に対するオン抵抗
の変動(typ)は「標準動作特性」のグラフに示されていま
す。オン抵抗の標準的な温度係数は0.5%/℃(typ)です。
電源シーケンスと過電圧保護
絶対最大定格を超えないようにしてください。定格を
超えるストレスにさらされた場合、デバイスに恒久的
に損傷を与える恐れがあります。CMOSデバイスでは、
常に適正な電源シーケンスが必要とされます。常にV+
を最初に印加し、次にV-を印加し(分割電源の場合)、そ
の後にアナログ信号やロジック入力を印加してくださ
い。これはアナログ信号やロジック信号に電流制限が
ないときには特に重要です。電源シーケンスを守れず、
かつアナログ信号やロジック入力の電流が30mA以下に
制限されていない場合は、図1に示すように小信号ダイ
オード(D1)を1個取付けてください。デュアル電源を
図1. ブロッキングダイオードを使用した過電圧保護
使用している場合、あるいはアナログ信号がGNDより
低くなる可能性がある場合は、小信号ダイオードを2個
(D1、D2)取付けてください(図1)。保護ダイオードを
取付けることでアナログ信号範囲が狭まり、D2により
V-よりダイオードドロップ分だけ高くなります。リーク
電流は、ダイオードを取付けることにより影響されま
せん。電源電圧が低い場合にはオン抵抗が少し増加し
ます。最大電源電圧(V-とV+の差)は17Vを超えないよう
にしてください。
保護ダイオードD1及びD2は過電圧保護の役割も果たし
ます。図1の回路で、電源電圧が絶対最大定格以下の場
合、絶対最大定格以下のフォルト電圧がアナログ信号
ピンに印加されても損傷は起きません。例えば、±5V
電源の場合、図1の回路は±8.5Vまでのアナログ信号に
耐えられます。フォルト信号が1つであれば、フォルト
電圧が+12Vあるいは-12Vに達しても損傷は起きません。
