ADA4807

Analog Devices · Operational amplifier · SOT-23-6

Single low-noise op-amp with a 180 MHz gain-bandwidth and 3.1 nV/rtHz input noise, in a SOT-23-6. Rail-to-rail output and a wide 2.7 to 10 V supply suit it to buffering ADC drivers and low-level sensor front ends, and a dedicated disable pin drops supply current for power-sensitive designs. A 225 V/us slew rate handles fast edges. The single of the ADA4807 family (dual -2, quad -4).

Pinout

Pin Name Type Function
1 VOUT output Amplifier output. Rail-to-rail output stage; saturated swing typically within ~40 mV of each rail with RLOAD = 1 kOhm. Linear output current ~50 mA sourcing / 60 mA sinking.
2 -VS power_in Negative supply. Connect to ground for single-supply operation or to the negative rail for dual-supply operation. Total supply range 2.7 V to 11 V (+VS - -VS).
3 +IN input Noninverting analog input. Rail-to-rail input common-mode range from -VS - 0.2 V to +VS + 0.2 V. Input bias current typically -1.2 uA, differential input resistance 35 kOhm.
4 -IN input Inverting analog input. Used with external feedback network to set closed-loop gain. Same input characteristics as +IN; keep absolute differential voltage below +/-1.4 V (per absolute maximum ratings).
5 DISABLE input Active-low power-down input. Logic low (<1.3 V) disables the amplifier (quiescent current drops to ~2.4 uA); logic high (>1.7 V) enables normal operation. Disable on time ~1.3 us, off time ~270 ns at +/-5 V.
6 +VS power_in Positive supply. Fully specified at +3 V, +5 V, and +/-5 V; operating range 2.7 V to 11 V total (+VS relative to -VS). PSRR typically 107 dB (positive) and 120 dB (negative).
