NJM1496

NJM1496 DOUBLE BALANCED MODULATION / DEMODULATOR ■ GENERAL DESCRIPTION The NJM1496 is a double balanced modulator-demodulator which produces an output voltage proportional to hte product of an input (signal) voltage and a switching (carrier) signal. Typical applications include suppressed carrier modulation, amplitude modulation, synchronous detection, FM or PM detection, broadband frequency doubling and chopping. ■ FEATURES ● Excellent carrier suppression 65dB typical at 0.5MHz 50dB typical at 10MHz ● Adjustable gain and signal handling ● Fully balanced inputs and outputs ● High Common Mode Rejection 85dB Typ. ● Package Outline DIP14, DMP14, SSOP14 ● Bipolar Technology ■ APPLICATION ● Balanced Modulation ● Synchronous Detection ● FM Detection ● Phase Detection ● Sampling ■ PIN CONFIGURATION ■ PACKAGE OUTLINE NJM1496D NJM1496M NJM1496V NJM1496D NJM1496M NJM1496V ■ EQUIVALENT CIRCUIT Ver.2003-12-09 -1- NJM1496 ■ ABSOLUTE MAXIMUM RATINGS PARAMETER Applied Voltage Carrier Input Voltage Signal Input Voltage Input Signal Bias Current (I5) Power Dissipation RATINGS 30 (Applied Pins 6-8, 12-8, 6-10, 12-10, 10-1, 8-1, 10-4, 8-4, 2-5, 3-5) ±5 (Applied Pins 8-10) ±(5+I5, Re) (Applied Pins 1-4) 5 10 (DIP14) 570 (DMP14) 300 (SSOP14) 300 -20 to +75 -40 to +125 (Ta=25°C) UNIT V V V V mA mW mW mW °C °C Operating Temperature Range Storage Temperature Range ■ ELECTRICAL CHARACTERISTICS PARAMETER Single-Ended Input Impedance Parallel Input Resistance Parallel Input Capacitance Single-Ended Output Impedance Parallel Output Resistance Parallel Output Capacitance Input Bias Current Ibs=I1+I4 / 2 Ibs=I8+I10 / 2 Input Offset Current Iios=I1 - I4 Iios=I8 - I10 Average Temperature Coefficient of Input Offset Current Output Offset Current (I6 - I12) Average Temperature Coefficient of Output Offset Current Output Voltage Operating Current (I6 + I12) I14 DC Power Dissipation DC characteristics (V+=12V, V-=-8V, I5=1.0mA, RL=3.9kΩ, Re=1.0kΩ, Ta=25°C) SYMBOL Rip Cip Rop Cop Ibs Ibc Iios Iioc ∆Iio IOC ∆IOC VO ID+ IDPD TEST CONDITION Signal Port, f =5.0MHz Signal Port, f =5.0MHz f =10MHz f =10MHz MIN.
