NJM2719

NJM2719 Low Noise, High-Speed Dual Operational Amplifier ■ GENERAL DESCRIPTION The NJM2719 is a dual high speed voltage feedback operational amplifier specifically optimized for low voltage noise. A voltage noise specification of 2.5nV/√Hz Typ. (at f =100kHz), a unity gain of 100MHz combine to make the NJM2719 an ideal choice for I/Q baseband amplifier, RFID reader application and other in wireless communication system desighns. The NJM2719 is available in the 8-pin SO package (DMP8) with standard pinouts. For compact layouts, the dual is also available in a tiny dual fine pitch 8-pin package (SSOP8, TVSP8). ■PACKAGE OUTLINE NJM2719M (DMP8) NJM2719V (SSOP8) NJM2719RB1 (TVSP8) ■ FEATURES ●Low Noise ●Unity Gain Bandwidth ●Phase Margin ●Slew Rate ●Output Rail-to-Rail ●Operating Voltage ●Bipolar Technology ●Package Outline Vni = 2.5nV/√Hz typ. at f=100kHz Vni = 3nV/√Hz typ. at f=10kHz fT = 100MHz typ. at V+/V- = ±5V fT = 90MHz typ. at V+/V- = ±2.5V Φm = 60deg typ. 60V/µs typ. at V+/V- = ±5V 35V/µs typ. at V+/V- = ±2.5V VOH ≥ +4.7V, VOL ≤ -4.8V at V+/V- = ±5V VOH ≥ +2.4V, VOL ≤ -2.4V at V+/V- = ±2.5V ±2.5V ~ ±5V DMP8 [NJM2719M] SSOP8 [NJM2719V] TVSP8 [NJM2719RB1] ■ APPLICATION ●Wireless Communication Equipment ●I/Q Baseband Application ●RFID Reader Application ●Active Filter ●ADC/DAC Buffer ●Ultrasound Amplifier ■ PIN CONFIGURATION ( Top View ) A OUTPUT A -INPUT A +INPUT V- 1 2 3 4 -+ +- 8 7 6 5 V+ B OUTPUT B -INPUT B +INPUT DMP8 [NJM2719M] SSOP8 [NJM2719V] TVSP8 [NJM2719RB1] Ver.2011-02-04 -1- NJM2719 ■ ABSOLUTE MAXIMUM RATINGS (Ta=25˚C) PARAMETER Supply Voltage Common Mode Input Voltage Range Differential Input Voltage Range SYMBOL V+ VICM VID RATINGS + 5.5 ± 5.5 (Note1) ±3 3 70 [DMP8],310 [SSOP8], 400[TVSP8] Power Dissipation PD 4 70[DMP8](Note2),410[SSOP8](Note2), 510[TVSP8] (Note2) -40 to +85 -50 to +150 UNIT V V V mW mW ˚C ˚C Operating Temperature Range Storage Temperature Range T opr T st g (Note 1) The output voltage of normal operation will be the Output Voltage Swing of electrical characteristics.

In the case of using the NJM2719 for these configurations, it is necessary to care about unwanted oscillation. An effective way to improve stability and to avoid oscillation is to add an isolation resistor as shown in Figure 1. Figure 2 shows required resistor values (RISO) for stability versus load capacitances (CL) in the unity-gain configuration (Figure 1). To ensure the stability, add a larger isolation resistor in Figure 2. (Resistor values in Figure2 are reference values when parasitic capacitance of an evaluation board is minimized.) 25 Supply Voltage ±5V 20 VIN R ISO VOUT CL RISO [Ω] 15 Supply Voltage ±2.5V + 10 5 Figure 1. 0 0 20 40 60 80 100 CL [pF] Figure 2.
