Data Sheet ZJA3100 Precision High Speed Fully Differential Amplifier Features             General Description The ZJA3100 is a broadband fully differential amplifier. The gain of the amplifier is set by two pairs of matched resistors. The ZJA3100 is significant advancement over simple op amps for driving various differential input ADCs or for driving signals over long lines. Broad Power Supply Range: 3 V to 15 V Low Power: 4.6 mA High Bandwidth: 145 MHz High Slew Rate: 447 V/µ s Low Input Offset Voltage: 50 µ V max (B grade) 110 µ V max from -40 ° C to +125 ° C (B grade) Low Input Offset Current: max 70 nA Low Noise: 2.9 nV/ Hz , f = 100 kHz Wide Input Common-mode Range: (-VS) – 0.4 V to (+VS) – 1 V Wide Output Common Mode Control: (-VS) + 1 V to (+VS) – 1 V Rail-to-rail Output Low Harmonic Distortion: -133 dBc HD2 and -140 dBc HD3 at 1 kHz Fast Settling Time 18-bit: 100 ns 16-bit: 50 ns The ZJA3100 offers a -3 dB bandwidth of 145 MHz while consuming merely 4.6 mA supply current. It eliminates the need for a BALUN typically required by high performance high speed ADCs, achieving outstanding low frequency and dc accuracy in terms of input voltage and current offset. The common-mode level of the differential output is programmable by VOCM pin, with a wide range within 1 V to either rail, easily level shifting the input signals for driving single supply differential input ADCs. The combination of these features also makes ZJA3100 ideal driver for high performance SAR ADCs and Σ-Δ ADCs, which demands both DC precision and fast settling time for the large sampling cap of ADC. The ZJA3100 may serve as differential line driver for high speed signals over low cost twisted pair or coaxial cables. The wide supply range lends itself well to extensive general applications, such as analog or digital video signaling. The external feedback network can be optimized to boost the high frequency components of the signal in order to accommodate low pass filtering of the signal channel. The ZJA3100 yields significant cost saving, performance enhancement and area reduction over discrete line driver solutions.
