LT1469IDF-2#TRPBF

LT1469-2 Dual 200MHz, 30V/µs 16-Bit Accurate AV ≥ 2 Op Amp FEATURES DESCRIPTION n The LT®1469-2 is a dual, precision high speed operational amplifier with 16-bit accuracy, decompensated to be stable in a gain of 2 or greater. The combination of precision and AC performance makes the LT1469-2 the optimum choice for high accuracy applications such as DAC current-to-voltage conversion and ADC buffers. The initial accuracy and drift characteristics of the input offset voltage and inverting input bias current are tailored for inverting applications. n n n n n n n n n n n n n n Stable in Gain AV ≥ 2 (AV = –1) 200MHz Gain Bandwidth Product 30V/μs Slew Rate Settling Time: 800ns (150μV, 10V Step) Specified at ±5V and ±15V Supplies Maximum Input Offset Voltage: 125μV Low Distortion: –96.5dB for 100kHz, 10VP-P Maximum Input Offset Voltage Drift: 3μV/°C Maximum Inverting Input Bias Current: 10nA Minimum DC Gain: 300V/mV Minimum Output Swing into 2k: ±12.8V Input Noise Voltage: 5nV/√Hz Input Noise Current: 0.6pA/√Hz Total Input Noise Optimized for 1kΩ < RS < 20kΩ Available in 8-Lead Plastic SO and 12-Lead (4mm × 4mm) DFN Packages The 200MHz gain bandwidth ensures high open-loop gain at frequency for reducing distortion. In noninverting applications such as an ADC buffer, the low distortion and DC accuracy allow full 16-bit AC and DC performance. The high slew rate of the LT1469-2 improves large-signal performance in applications such as active filters and instrumentation amplifiers compared to other precision op amps. APPLICATIONS n n n n n n The LT1469-2 is specified on power supply voltages of ±5V and ±15V and from –40°C to 85°C. It is available in an 8-lead SOIC package and a space saving 4mm × 4mm leadless package. For a unity-gain stable op amp with same DC performance, see the LT1469 datasheet.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The inputs are protected by back-to-back diodes and two 100Ω series resistors. If the differential input voltage exceeds 0.7V, the input current should be limited to less than 10mA. Input voltages outside the supplies will be clamped by ESD protection devices and input currents should also be limited to less than 10mA. Note 3: A heat sink may be required to keep the junction temperature below absolute maximum when the output is shorted indefinitely. Note 4: The LT1469C-2 and LT1469I-2 are guaranteed functional over the operating temperature range of – 40°C to 85°C. Note 5: The LT1469C-2 is guaranteed to meet specified performance from 0°C to 70°C and is designed, characterized and expected to meet specified performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The LT1469I-2 is guaranteed to meet specified performance from –40°C to 85°C. Note 6: Slew rate is measured between ±8V on the output with ±12V swing for ±15V supplies and ±2V on the output with ±3V swing for ±5V supplies. Tested in AV = –10 Note 7: Full-power bandwidth is calculated from the slew rate. FPBW = SR/2πVP. Note 8: This parameter is not 100% tested. Note 9: ΔCMRR and ΔPSRR are defined as follows: 1) CMRR and PSRR are measured in μV/V on each amplifier; 2) the difference between the two sides is calculated in μV/V; 3) the result is converted to dB.
