Coupled with a power-saving mode – Power Down Mode: 0.5 µA Typ) that reduces current to less than 1.5 μA, these • Bandwidth: 205 MHz devices offer an attractive solution for high-frequency amplifiers in battery-powered applications. • Slew Rate: 560 V/µs • Rise Time: 3 ns (2 VSTEP) The OPA836 RUN package option includes integrated gain-setting resistors for the smallest • Settling Time (0.1%): 22 ns (2 VSTEP) possible footprint on a printed circuit board • Overdrive Recovery Time: 60 ns (approximately 2 mm × 2 mm). By adding circuit • SNR: 0.00013% (–117.6 dBc) at 1 kHz (1 VRMS) traces on the PCB, gains of +1, –1, –1.33, +2, +2.33, • THD: 0.00003% (–130 dBc) at 1 kHz (1 VRMS) –3, +4, –4, +5, –5.33, +6.33, –7, +8 and inverting attenuations of –0.1429, –0.1875, –0.25, –0.33, –0.75 • HD2/HD3: –85 dBc/–105 dBc at 1 MHz (2 VPP) can be achieved. See Table 3 and Table 4 for details. • Input Voltage Noise: 4.6 nV/ √Hz (f = 100 kHz) The OPA836 and OPA2836 devices are • Input Offset Voltage: 65 µV (±400-µV Max) characterized for operation over the extended • CMRR: 116 dB industrial temperature range of –40°C to 125°C. • Output Current Drive: 50 mA Device Information(1) • RRO: Rail-to-Rail Output PART NUMBER PACKAGE BODY SIZE (NOM) • Input Voltage Range: –0.2 V to +3.9 V SOT-23 (6) 2.90 mm × 1.60 mm (5-V Supply) OPA836 WQFN (10) 2.00 mm × 2.00 mm • Operating Temperature Range: SOIC (8) 4.90 mm × 3.91 mm –40°C to +125°C VSSOP (10) 3.00 mm × 3.00 mm OPA2836 2 Applications UQFN (10) 2.00 mm × 2.00 mm WQFN (10) 2.00 mm × 2.00 mm • Low-Power Signal Conditioning (1) For all available packages, see the package option addendum • Audio ADC Input Buffers at the end of the data sheet. • Low-Power SAR and ΔΣ ADC Drivers • Portable Systems Harmonic Distortion vs Frequency • Low-Power Systems • High-Density Systems 3 Description The OPA836 and OPA2836 devices are single- and dual-channel, ultralow power, rail-to-rail output, negative-rail input, voltage-feedback operational amplifiers designed to operate over a power-supply range of 2.5 V to 5.5 V (single supply), or ±1.25 V to ±2.75 V (dual supply). Consuming only 1 mA per channel and a unity gain bandwidth of 205 MHz, these amplifiers set an industry-leading power-to- performance ratio for rail-to-rail amplifiers. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
