@@ -0,0 +1,49 @@+# 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). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Low-noise rail-to-rail op-amp |+| Gain-bandwidth | 180 MHz |+| Input voltage noise | 3.1 nV/rtHz |+| Slew rate | 225 V/us |+| Supply | 2.7-10 V |+| Output | Rail-to-rail |+| Disable | Yes (pin 5) |+| Package | SOT-23-6 |++## Ordering variants++- `ADA4807-1ARJZ (SOT-23-6, tape & reel)`++## CAD (KiCad official)++- Symbol: `Amplifier_Operational:ADA4807-1 (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://www.analog.com/media/en/technical-documentation/data-sheets/ADA4807-1_4807-2_4807-4.pdf) (33 pp, sha256 `8f615c78af71a04a`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
