SLOS712D –JANUARY 2011–REVISED OCTOBER 2011

Very Low-Power, Rail-to-Rail Out, Negative Rail In, VFB Op Amp

Check for Samples: OPA836, OPA2836

FEATURES

DESCRIPTION

Fabricated using the industry-leading BiCom-3x

(SiGe complimentary bipolar) process, the OPA836

and OPA2836 are single and dual ultra low-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

and ±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.

•

Low Power

–

Supply Voltage: 2.5 V to 5.5 V

Quiescent Current: 1 mA (Typ)

Power Down Mode: 0.5µA Ttyp)

•

Bandwidth: 205 MHz

Slew Rate: 560 V/µs

Rise Time: 3 ns (2 V_STEP

)

Settling Time: 22 ns (2 V_STEP

)

For battery powered portable applications where

power is of key importance, the OPA836's and

OPA2836's low power consumption and high

frequency performance offers designers performance

versus power not attainable in other devices. Coupled

with a power savings mode to reduce current to <1.5

μA, the device offers an attractive solution for high

frequency amplifiers in battery powered applications.

Overdrive Recovery Time: 60ns

SNR: 0.00013% (–117.6 dBc) at 1 kHz (1 V_RMS

)

THD: 0.00003% (–130 dBc) at 1 kHz (1 V_RMS

)

HD₂/HD₃: –85dBc / -105 dBc at 1 MHz (2 Vpp)

Input Voltage Noise: 4.6 nV/rtHz (f = 100 kHz)

Input Offset Voltage: 65 µV (400 µV Max)

CMRR: 116 dB

The OPA836 and OPA2836 are offered in following

package options:

Output Current Drive: 50 mA

RRO – Rail-to-Rail Output

•

OPA836 Single: SOT23-6 (DBV), and 10 pin

WQFN (RUN) with integrated gain resistors.

Input Voltage Range: -0.2 V to 3.9 V

(5 V Supply)

•

OPA2836 Dual: SOIC-8 (D), VSSOP (MSOP) -10

(DGS), and 10 pin WQFN (RUN).

•

Operating Temperature Range:

-40°C to +125°C

The OPA836 RUN package option includes

integrated gain setting resistors for smallest possible

footprint on a printed circuit board (≈ 2mm x 2mm).

By adding circuit traces on the PCB, gains of +1, -1,

-1.33, +2, +2.33, -3, +4, -4, +5, -5.33, +6.33, -7, +8

and inverting attenuations of -0.1429, -0.1875, -0.25,

-0.33, -0.75 can be achieved. See the Application

Information section for details.
