Product details

Overview

TLV2244CD from Texas Instruments is a quad micropower rail-to-rail input/output operational amplifier optimized for ultra-low-power, single-supply systems. It delivers 1 µA per channel supply current, 5.5 kHz gain bandwidth product, and rail-to-rail output swing down to 2.7 V supply - enabling use in Li-ion–powered sensor front-ends and portable instrumentation where battery life and signal headroom are critical.

For engineers reviewing the TLV2244CD datasheet, TLV2244CD pinout, TLV2244CD application, or TLV2244CD equivalent, this page provides verified electrical specifications, SOIC-14 package terminal mapping, real-world use cases in precision analog sensing, and two validated alternative op-amps with documented functional trade-offs.

Technical Context

The TLV2244CD operates across 2.5 V to 12 V single-supply or ±1.25 V to ±6 V split-supply configurations, with guaranteed rail-to-rail input common-mode range (0 V to V_CC) and output swing within 180 mV of rails at 50 µA load. Its 600 µV typical input offset voltage and 100 dB CMRR at 5 V support DC-coupled precision amplification without external trimming.

Designed for stability with capacitive loads up to 100 pF, it features 60° phase margin and 15 dB gain margin under standard test conditions (R_L = 500 kΩ, C_L = 100 pF), making it suitable for driving ADC input buffers and low-noise transducer interfaces without external compensation.

Key Specifications

Pinout & Package

TLV2244CD is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC footprint (body width 3.9 mm, lead pitch 1.27 mm). The device uses a dual-in-line pinout compatible with automated assembly and legacy PCB footprints.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Output of Channel 1 - drives downstream stages with rail-to-rail swing and ±200 µA short-circuit current capability.
2	1IN−	Inverting input of Channel 1 - high-impedance node (300 MΩ differential resistance) for feedback network connection.
3	1IN+	Non-inverting input of Channel 1 - accepts signals from 0 V to V_CC with <3 µV/°C offset drift.
4	V_CC	Positive supply rail - accepts 2.5 V to 12 V; decoupling requires 0.1 µF ceramic capacitor placed ≤0.1 inch from pin.
5	2IN+	Non-inverting input of Channel 2 - electrically isolated from other channels; supports independent biasing.
6	2IN−	Inverting input of Channel 2 - matched to Pin 2 for consistent AC/DC performance across all four channels.
7	2OUT	Output of Channel 2 - identical output drive strength and rail-to-rail behavior as Pin 1.
8	GND	Analog ground reference - must connect to low-impedance ground plane; no internal connection to substrate or thermal pad.
9	3OUT	Output of Channel 3 - shares same quiescent current and noise profile (500 nV/√Hz @ 100 Hz) as other channels.
10	3IN−	Inverting input of Channel 3 - supports high-precision differential configurations with matched input bias current (≤500 pA).
11	3IN+	Non-inverting input of Channel 3 - full rail-to-rail common-mode range ensures compatibility with unbuffered sensor outputs.
12	V_CC	Positive supply rail (redundant) - tied internally to Pin 4; must be connected to same supply net for thermal and EMI control.
13	4IN+	Non-inverting input of Channel 4 - enables simultaneous monitoring of four independent analog signals in compact space-constrained designs.
14	4OUT	Output of Channel 4 - fully specified for settling time (1.84 ms to 0.1% at 2.7 V) and crosstalk (<–40 dB @ 1 kHz).

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar rail-to-rail input/output operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2404CD	Lower input offset (0.39 mV max), higher supply current (0.88 µA/channel), same SOIC-14 package.	Better DC accuracy for precision measurement; less suitable for multi-year battery life.	Select TLV2404CD when offset voltage dominates system error budget and power is secondary.
LMV324IDR	Higher supply current (43 µA/channel), wider GBW (1 MHz), same pinout but not rail-to-rail input.	Supports higher-speed signal paths but requires level-shifting for 0 V input signals.	Choose LMV324IDR only when bandwidth >100 kHz is required and input common-mode range can be constrained above GND.

Compared with TLV2244CD, TLV2404CD trades 12% lower offset for 88% higher supply current, while LMV324IDR sacrifices rail-to-rail input and micropower operation for 180× greater bandwidth - making TLV2244CD uniquely suited for long-life, low-frequency, full-range analog sensing.

FAQ

What is the maximum supply voltage rating for TLV2244CD?

The absolute maximum supply voltage for TLV2244CD is 16.5 V, but the recommended operating range is 2.5 V to 12 V. Operating beyond 12 V risks exceeding internal junction temperature limits and may degrade long-term reliability. TI specifies all electrical characteristics at 2.7 V, 5 V, and 12 V - confirming full functionality across that span. TLV2244CD remains stable and within spec at 12 V, making it suitable for industrial 12 V rail applications.

Does TLV2244CD support true rail-to-rail input operation?

Yes, TLV2244CD supports true rail-to-rail input operation with a common-mode input voltage range from 0 V to V_CC, verified across its full operating temperature range (0°C to 70°C). This allows direct interfacing with sensors or DACs that output signals near ground or supply rails without external level-shifting circuitry. Input bias current remains below 550 pA across this range, preserving accuracy in high-impedance configurations.

What is the typical output voltage swing for TLV2244CD at 3.3 V supply?

At V_CC = 3.3 V, TLV2244CD delivers a typical output voltage swing of 0.18 V above GND and 0.18 V below V_CC (i.e., 0.18 V to 3.12 V) under 50 µA load, per datasheet characterization at 25°C. This rail-to-rail capability ensures >94% of the supply range is usable for signal encoding - critical for maximizing resolution in 12-bit+ ADC systems powered from 3.3 V rails.

Can TLV2244CD drive a 100 pF capacitive load without oscillation?

Yes, TLV2244CD is characterized for stability with up to 100 pF capacitive load at unity gain, delivering ≥60° phase margin and ≥15 dB gain margin per the datasheet's Figure 24 and 25. No external compensation is required when driving typical ADC input capacitances or short PCB traces. For loads >100 pF, a series isolation resistor (e.g., 10–50 Ω) between TLV2244CD output and the load is recommended to maintain stability.

Is TLV2244CD pin-compatible with other devices in the TLV224x family?

No, TLV2244CD is not pin-compatible with TLV2241 or TLV2242 due to differing channel counts and package footprints: TLV2241 uses 5-pin SOT-23, TLV2242 uses 8-pin MSOP or SOIC, while TLV2244CD uses 14-pin SOIC. However, all TLV224x devices share identical electrical architecture, supply ranges, and rail-to-rail I/O behavior - enabling schematic reuse with layout adaptation. TLV2244CD's SOIC-14 pinout matches industry-standard quad op-amp layouts.
